Example Questions
Example Question #1 : Laws Of Exponents
Simplify:
When dividing terms with the same bases, remember to subtract the exponents.
Keep in mind that when there is a negative exponent in the numerator, putting that term in the denominator will make the exponent positive.
Example Question #2 : Laws Of Exponents
Evaluate
We first need to apply the Exponent Rule to our two terms.
Then we do subtraction to obtain our final answer,
Example Question #3 : Laws Of Exponents
Simplify the following expression:
The correct answer is 
First we can start by simplifying the 'x' terms. We start with 
Now we can simplify the 'y' terms as follows: 
Last, the 'z' terms can be simplified as follows: 
This leaves us with the final simplified answer of 
Example Question #1 : Laws Of Exponents
Which of the following is equivalent to 
Since all of the answer choices look like 
Then,
When you have an exponent being raised to an exponent, multiply the exponents together.
Example Question #1 : Laws Of Exponents
What is 
When terms with the same base are multiplied, multiply the coefficients together then add up all the exponents.
For the coefficients:
For the exponents:
Thus, the answer is
Example Question #13 : Operations In Expressions
Start by simplifying the numerator.
When an exponent is raised to another exponent, multiply the two exponents together.
Now, tackle the denominator. When two numbers of the same base are multiplied, you want to add the exponents.
Put the numerator and denominator together:
When you have a fraction with terms that have the same base, you want to subtract the exponent in the denominator from the exponent in the numerator.
To make a term with a negative exponent in the numerator positive, put it in the denominator.
