Question 1 :
Simplify (7)² x (3)³
Solution :
Since the power of 7 is even, the answer must have positive sign. So it is enough to multiply 7 two times.
(7)^{2} = 7 x 7 ==> 49
Since the power of 3 is odd, the answer will have negative sign.
(3)^{3} = 3 x 3 x 3 ==> 27
(7)^{2} x (3)^{3} = 49 x (27) ==> 1323
So, the answer is 1323

So, the answer is 1/64.
Question 4 :
Simplify (3)^{4} x (5/3)^{4}
Solution :
(3)⁴ x (5/3)⁴
= (3)⁴ x (5⁴/3⁴)

Simplify by Using the Product, Quotient, and Power Rules
Learning Objective(s)
· Use the product rule to multiply exponential expressions with like bases.
· Use the power rule to raise powers to powers.
· Use the quotient rule to divide exponential expressions with like bases.
· Simplify expressions using a combination of the properties.
Exponential notation was developed to write repeated multiplication more efficiently. There are times when it is easier to leave the expressions in exponential notation when multiplying or dividing. Let’s look at rules that will allow you to do this.
The Product Rule for Exponents
Recall that exponents are a way of representing repeated multiplication. For example, the notation 5^{4} can be expanded and written as 5 • 5 • 5 • 5, or 625. And don’t forget, the exponent only applies to the number immediately to its left, unless there are parentheses.
What happens if you multiply two numbers in exponential form with the same base? Consider the expression (2^{3})(2^{4}). Expanding each exponent, this can be rewritten as (2 • 2 • 2) (2 • 2 • 2 • 2) or 2 • 2 • 2 • 2 • 2 • 2 • 2. In exponential form, you would write the product as 2^{7}. Notice, 7 is the sum of the original two exponents, 3 and 4.
What about (x^{2})(x^{6})? This can be written as (x • x)(x • x • x • x • x • x) = x • x • x • x • x • x • x • x or x^{8}. And, once again, 8 is the sum of the original two exponents.
To multiply exponential terms with the same base, simply add the exponents.
Example  
Problem  Simplify. (a^{3})(a^{7}) 

 (a^{3})(a^{7})  The base of both exponents is a, so the product rule applies. 
 a^{3+7}  Add the exponents with a common base. 
(a^{3})(a^{7}) = a^{10} 

When multiplying more complicated terms, multiply the coefficients and then multiply the variables.
Example  
Problem  Simplify. 5a^{4}· 7a^{6} 

 35 ·a^{4 }·a^{6}  Multiply the coefficients. 
 35 ·a^{4+6}  The base of both exponents is a, so the product rule applies. Add the exponents. 
 35 ·a^{10}  Add the exponents with a common base. 
Answer  5a^{4}· 7a^{6 = }35a^{10} 

Simplify the expression, keeping the answer in exponential notation.
(4x^{5})( 2x^{8})
A) 8x^{5} • x^{8} B) 6x^{13} C) 8x^{13} D) 8x^{40}
Show/Hide Answer A) 8x^{5} • x^{8} Incorrect. 8x^{5}• x^{8}is equivalent to (4x^{5})(2x^{8}), but it still is not in simplest form. Simplify x^{5}•x^{8} by using the Product Rule to add exponents. The correct answer is 8x^{13}.
B) 6x^{13} Incorrect. 6x^{13 }is not equivalent to (4x^{5})(2x^{8}). In this incorrect response, the correct exponents were added, but the coefficients were also added together. They should have beenmultiplied. The correct answer is 8x^{13}.
C) 8x^{13} Correct. 8x^{13 }is equivalent to (4x^{5})(2x^{8}). Multiply the coefficients (4 • 2) and apply the Product Rule to add the exponents of the variables (in this case x) that are the same.
D) 8x^{40} Incorrect. 8x^{40 }is not equivalent to (4x^{5})(2x^{8}). Do not multiply the coefficients and the exponents. Remember, using the Product Rule add the exponents when the bases are the same. The correct answer is 8x^{13}.

The Power Rule for Exponents
Let’s simplify (5^{2})^{4}. In this case, the base is5^{2 }and the exponent is 4, so you multiply 5^{2 }four times:(5^{2})^{4 } = 5^{2 }•^{}5^{2 }•5^{2 }•5^{2 = }5^{8 }(using the Product Rule – add the exponents).
(5^{2})^{4 }isa power of a power. It is the fourth power of 5 to the second power. And we saw above that the answer is 5^{8}. Notice that the new exponent is the same as the product of the original exponents: 2 •4 = 8.
So, (5^{2})^{4 }= 5^{2 }^{•}^{}^{4}^{} = 5^{8 }(which equals 390,625, if you do the multiplication).
Likewise, (x^{4})^{3} = x^{4 • 3} = x^{12}.
This leads to another rule for exponents—the Power Rule for Exponents. To simplify a power of a power, you multiply the exponents, keeping the base the same. For example, (2^{3})^{5} = 2^{15}.
The Power Rule for Exponents
For any positive number x and integers a and b: (x^{a})^{b}= x^{a}^{·}^{ b}. ^{ }

Example  
Problem  Simplify. 6(c^{4})^{2} 

 6(c^{4})^{2}  Since you are raising a power to a power, apply the Power Rule and multiply exponents to simplify. The coefficient remains unchanged because it is outside of the parentheses. 
Answer  6(c^{4})^{2 }=6c^{8} 

Example  
Problem  Simplify. a^{2}(a^{5})^{3} 

 _{}  Raise a^{5} to the power of 3 by multiplying the exponents together (the Power Rule). 
 _{}  Since the exponents share the same base, a, they can be combined (the Product Rule). 
 _{} 

Answer  _{} 

Simplify: _{}
A) _{}
B) _{}
C) _{}
D) _{}
Show/Hide Answer A) _{} Incorrect. This expression is not simplified yet. Recall that –a can also be written –a^{1}. Multiply –a^{1} by a^{8} to arrive at the correct answer. The correct answer is _{}.
B) _{} Incorrect. Do not add the exponents of 2 and 4 together. The Power Rule states that for a power of a power you multiply the exponents. The correct answer is _{}.
C) _{} Incorrect. Do not add the exponents of 2 and 4 together. The Power Rule states that for a power of a power you multiply the exponents. The correct answer is _{}.
D) _{} Correct. Using the Power Rule, _{}.

The Quotient Rule for Exponents
Let’s look at dividing terms containing exponential expressions. What happens if you divide two numbers in exponential form with the same base? Consider the following expression.
_{}
You can rewrite the expression as: _{}. Then you can cancel the common factors of 4 in the numerator and denominator: _{}
Finally, this expression can be rewritten as 4^{3} using exponential notation. Notice that the exponent, 3, is the difference between the two exponents in the original expression, 5 and 2.
So, _{} = 4^{52} = 4^{3}.
Be careful that you subtract the exponent in the denominator from the exponent in the numerator.
_{}
or
_{} = x^{7}^{−}^{9} = x^{2}
So, to divide two exponential terms with the same base, subtract the exponents.
Notice that _{} = 4^{0}. And we know that _{} = _{} = 1. So this may help to explain why 4^{0 }= 1.
Example  
Problem  Evaluate. _{} 

 _{}  These two exponents have the same base, 4. According to the Quotient Rule, you can subtract the power in the denominator from the power in the numerator. 
_{}= 4^{5} 

When dividing terms that also contain coefficients, divide the coefficients and then divide variable powers with the same base by subtracting the exponents.
Example  
Problem  Simplify. _{} 

 _{}  Separate into numerical and variable factors. 

_{}  Since the bases of the exponents are the same, you can apply the Quotient Rule. Divide the coefficients and subtract the exponents of matching variables. 
Answer  _{}=_{} 

All of these rules of exponents—the Product Rule, the Power Rule, and the Quotient Rule—are helpful when evaluating expressions with common bases.
Example  
Problem  Evaluate _{} when x = 4. 


_{}  Separate into numerical and variable factors. 

_{}  Divide coefficients, and subtract the exponents of the variables. 
 _{}  Simplify. 
 _{}  Substitute the value 4 for the variable x. 
Answer  _{}= 768 

Usually, it is easier to simplify the expression before substituting any values for your variables, but you will get the same answer either way.
Example  
Problem  Simplify._{} 

 _{}  Use the order of operations with PEMDAS: E: Evaluate exponents. Use the Power Rule to simplify (a^{5})^{3}. 
 _{} 

 _{}  M: Multiply, using the Product Rule as the bases are the same. 
 _{} 

 _{}  D: Divide using the Quotient Rule. 
_{} =_{} 

There are rules that help when multiplying and dividing exponential expressions with the same base. To multiply two exponential terms with the same base, add their exponents. To raise a power to a power, multiply the exponents. To divide two exponential terms with the same base, subtract the exponents.

Evaluate Algebraic Expressions
In the last section, we simplified expressions using the order of operations. In this section, we’ll evaluate expressions—again following the order of operations.
To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.
Example \(\PageIndex{1}\): evaluate
Evaluate \(x + 7\) when
 \(x = 3\)
 \(x = 12\)
Solution
 To evaluate, substitute \(3\) for \(x\) in the expression, and then simplify.
\(x + 7\)  
Substitute.  \(\textcolor{red}{3} + 7\) 
Add.  \(10\) 
When \(x = 3\), the expression \(x + 7\) has a value of \(10\).
 To evaluate, substitute \(12\) for \(x\) in the expression, and then simplify.
\(x + 7\)  
Substitute.  \(\textcolor{red}{12} + 7\) 
Add.  \(19\) 
When \(x = 12\), the expression \(x + 7\) has a value of \(19\). Notice that we got different results for parts (a) and (b) even though we started with the same expression. This is because the values used for \(x\) were different. When we evaluate an expression, the value varies depending on the value used for the variable.

Example \(\PageIndex{2}\)
Evaluate \(9x − 2\), when
 \(x = 5\)
 \(x = 1\)
Solution
Remember \(ab\) means \(a\) times \(b\), so \(9x\) means \(9\) times \(x\).
 To evaluate the expression when \(x = 5\), we substitute \(5\) for \(x\), and then simplify.
\(9x  2\)  
Substitute \(\textcolor{red}{5}\) for x.  \(9 \cdot \textcolor{red}{5}  2\) 
Multiply.  \(45  2\)

 To evaluate the expression when \(x = 1\), we substitute \(1\) for \(x\), and then simplify.
\(9x  2\)  
Substitute \(\textcolor{red}{1}\) for x.  \(9 \cdot \textcolor{red}{1}  2\) 
Multiply.  \(9  2\) 
Subtract.  \(7\) 
Notice that in part (a) that we wrote \(9 • 5\) and in part (b) we wrote \(9(1)\). Both the dot and the parentheses tell us to multiply.

Example \(\PageIndex{6}\): evaluate
Evaluate \(2x^2 + 3x + 8\) when \(x = 4\).
Solution
We need to be careful when an expression has a variable with an exponent. In this expression, \(2x^2\) means \(2 • x • x\) and is different from the expression \((2x)^2\), which means \(2x • 2x\).
\(2x^{2} + 3x + 8\)  
Substitute \(\textcolor{red}{4}\) for each x.  \(2(\textcolor{red}{4})^{2} + 3(\textcolor{red}{4}) + 8\)

Identify Terms, Coefficients, and Like Terms
Algebraic expressions are made up of terms. A term is a constant or the product of a constant and one or more variables. Some examples of terms are \(7\), \(y\), \(5x^2\), \(9a\), and \(13xy\).
The constant that multiplies the variable(s) in a term is called the coefficient. We can think of the coefficient as the number in front of the variable. The coefficient of the term \(3x\) is \(3\). When we write \(x\), the coefficient is \(1\), since \(x = 1 • x\). Table \(\PageIndex{1}\) gives the coefficients for each of the terms in the left column.
Term  Coefficient 

7  7 
9a  9 
y  1 
5x^{2}  5 
An algebraic expression may consist of one or more terms added or subtracted. In this chapter, we will only work with terms that are added together. Table \(\PageIndex{2}\) gives some examples of algebraic expressions with various numbers of terms. Notice that we include the operation before a term with it.
Expression  Terms 

7  7

2x + 7y + 4  2x, 7y, 4 
3x^{2 }+ 4x^{2} + 5y + 3  3x^{2,} 4x^{2}, 5y, 3 
Example \(\PageIndex{7}\):
Identify each term in the expression \(9b + 15x^2 + a + 6\). Then identify the coefficient of each term.
Solution
The expression has four terms. They are \(9b\), \(15x^2\), \(a\), and \(6\).
The coefficient of \(9b\) is \(9\).
The coefficient of \(15x^2\) is \(15\).
Remember that if no number is written before a variable, the coefficient is \(1\). So the coefficient of a is \(1\).
The coefficient of a constant is the constant, so the coefficient of \(6\) is \(6\).
exercise \(\PageIndex{13}\)
Identify all terms in the given expression, and their coefficients: \(4x + 3b + 2\)
 Answer
The terms are \(4x, 3b,\) and \(2\). The coefficients are \(4, 3,\) and \(2\).
exercise \(\PageIndex{14}\)
Identify all terms in the given expression, and their coefficients: \(9a + 13a^2 + a^3\)
 Answer
The terms are \(9a, 13a^2,\) and \(a^3\), The coefficients are \(9, 13,\) and \(1\).
Some terms share common traits. Look at the following terms. Which ones seem to have traits in common?
\(5x, 7, n^{2}, 4, 3x, 9n^{2}\)
Which of these terms are like terms?
 The terms \(7\) and \(4\) are both constant terms.
 The terms \(5x\) and \(3x\) are both terms with \(x\).
 The terms \(n^2\) and \(9n^2\) both have \(n^2\).
Terms are called like terms if they have the same variables and exponents. All constant terms are also like terms. So among the terms \(5x, 7, n^2, 4, 3x, 9n^2, 7\) and \(4\) are like terms, \(5x\) and \(3x\) are like terms, and \(n^2\) and \(9n^2\) are like terms.
Definition: Like terms
Terms that are either constants or have the same variables with the same exponents are like terms.
Example \(\PageIndex{8}\): identify
Identify the like terms:
 \(y^3, 7x^2, 14, 23, 4y^3, 9x, 5x^2\)
 \(4x^2 + 2x + 5x^2 + 6x + 40x + 8xy\)
Solution
 \(y^3, 7x^2, 14, 23, 4y^3, 9x, 5x^2\)
Look at the variables and exponents. The expression contains \(y^3, x^2, x\), and constants. The terms \(y^3\) and \(4y^3\) are like terms because they both have \(y^3\). The terms \(7x^2\) and \(5x^2\) are like terms because they both have \(x^2\). The terms \(14\) and \(23\) are like terms because they are both constants. The term \(9x\) does not have any like terms in this list since no other terms have the variable \(x\) raised to the power of \(1\).
 \(4x^2 + 2x + 5x^2 + 6x + 40x + 8xy\)
Look at the variables and exponents. The expression contains the terms \(4x^2, 2x, 5x^2, 6x, 40x\), and \(8xy\) The terms \(4x^2\) and \(5x^2\) are like terms because they both have \(x^2\). The terms \(2x, 6x\), and \(40x\) are like terms because they all have \(x\). The term \(8xy\) has no like terms in the given expression because no other terms contain the two variables \(xy\).
exercise \(\PageIndex{15}\)
Identify the like terms in the list or the expression: \(9, 2x^3, y^2, 8x^3, 15, 9y, 11y^2\)
 Answer
\(9, 15\); \(2x^3\) and \(8x^3\), \(y^2\), and \(11y^2\)
exercise \(\PageIndex{16}\)
Identify the like terms in the list or the expression: \(4x^3 + 8x^2 + 19 + 3x^2 + 24 + 6x^3\)
 Answer
\(4x^3\) and \(6x^3\); \(8x^2\) and \(3x^2\); \(19\) and \(24\)
Simplify Expressions by Combining Like Terms
We can simplify an expression by combining the like terms. What do you think \(3x + 6x\) would simplify to? If you thought \(9x\), you would be right!
We can see why this works by writing both terms as addition problems.
Add the coefficients and keep the same variable. It doesn’t matter what \(x\) is. If you have \(3\) of something and add \(6\) more of the same thing, the result is \(9\) of them. For example, \(3\) oranges plus \(6\) oranges is \(9\) oranges. We will discuss the mathematical properties behind this later.
The expression \(3x + 6x\) has only two terms. When an expression contains more terms, it may be helpful to rearrange the terms so that like terms are together. The Commutative Property of Addition says that we can change the order of addends without changing the sum. So we could rearrange the following expression before combining like terms.
Now it is easier to see the like terms to be combined.
HOW TO: COMBINE LIKE TERMS
Step 1. Identify like terms.
Step 2. Rearrange the expression so like terms are together.
Step 3. Add the coefficients of the like terms.
Example \(\PageIndex{9}\): simplify
Simplify the expression: \(3x + 7 + 4x + 5\).
Solution
\(3x + 7 + 4x + 5\)  
Identify the like terms  \(\textcolor{red}{3x} + \textcolor{blue}{7} + \textcolor{red}{4x} + \textcolor{blue}{5}\) 
Rearrange the expression, so the like terms are together.  \(\textcolor{red}{3x} + \textcolor{red}{4x} + \textcolor{blue}{7} + \textcolor{blue}{5}\) 
Add the coefficients of the like terms.  \(\textcolor{red}{7x} + \textcolor{blue}{12}\) 
The original expression is simplified to...  \(7x + 12\)

 Answer
\(16x+17\)
exercise \(\PageIndex{18}\)
Simplify: \(5y + 2 + 8y + 4y + 5\)
 Answer

Example \(\PageIndex{10}\): simplify
Simplify the expression: \(7x^2 + 8x + x^2 + 4x\).
Solution
\(7x^{2} + 8x + x^{2} + 4x\)  
Identify the like terms.  \(\textcolor{red}{7x^{2}} + \textcolor{blue}{8x} + \textcolor{red}{x^{2}} + \textcolor{blue}{4x}\) 
Rearrange the expression so like terms are together.  \(\textcolor{red}{7x^{2}} + \textcolor{red}{x^{2}} + \textcolor{blue}{8x} + \textcolor{blue}{4x}\) 
Add the coefficients of the like terms.  \(\textcolor{red}{8x^{2}} + \textcolor{blue}{12x}\) 
These are not like terms and cannot be combined. So \(8x^2 + 12x\) is in simplest form.

How to Simplify Exponents
Multiply exponents by adding the exponents together. For example, x to the fifth power multiplied by x to the fourtth power equals x to the ninth power (x5 + x4 = x9), or (xxxxx)(xxxx) = (xxxxxxxxx).
Divide exponents by subtracting the exponents from each other. The equation x to the ninth power divided by x to the fifth power simplifies to x to the fourth power (x9 – x5 = x4), or (xxxxxxxxx)/(xxxxx) = (xxxx).
Simplify an exponent raised to another power by multiplying the exponents together. Simplifying x to the third power raised to the fourth power produces x to the 12th power [(x3)4 = x12], or (xxx)(xxx)(xxx)(xxx) = (xxxxxxxxxxxx).
Remember that any number to the 0th power equals one, meaning x to any power raised to the 0th power simplifies to one. Examples include x0 = 1, (x4)0 = 1, and (x5y3)0 = 1.
Note that equations with different variables such as x squared multiplied by y cubed (x2y3) cannot be combined to produce xy to the sixth power. This equation is already simplified. However, if the entire equation of x squared multiplied by y cubed is then squared, each of the variables is simplified separately, resulting in x to the fourth power multiplied by y to the sixth power (x2y3)2 = x4y6, or (xxxx)(yyyyyy).
