The first step to get help fast is to post the right question.
I believe that you have omitted parentheses, that is why you do not get meaningful help.
When you have an expression type-set like this:
\(\dfrac{4z^{a+2}}{-8z^{a-2}}\)
you have done the correct step of using a \(\div\) to represent the fraction.
There are other rules in PEMDAS you will need to follow (the same way you would like to calculate using a calculator).
If there are no parentheses, you need to execute the exponents a+2 and a-2 first, which means you would have to translate to
4z^(a+2)\(\div\)(-8z^(a-2)
which correctly tranlates the above expression to a single line.

I hope with this expression, either you will find the answer by yourself, or someone else will be able to help you.
