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.

Simplify the following expression:
Simplify the following expression:
The correct answer is 
due to the law of exponents. When solving this type of problem, it is easiest to focus on like terms (i.e. terms containing x or terms containing y).
First we can start by simplifying the 'x' terms. We start with 
which is equivalent to 
. We then are left 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 
.

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.
