Question

What is the answer to this?

Answer 1

The top and bottom of the fraction have the same number, raised to different powers.

In this situation, the answer is (the number) ^(difference between the powers)

7^(-5-7)=7^(-12)=1/7^12

Answer 2

7^-12 or 1/7^12

Explanation:

To divide exponents with the same base, subtract the second exponent from the first.

So:

7^-5/7^7 = 7^-5-7 = 7^-12

You can also write 7^-12 as 1/7^12.
