Rewrite the expression using each base only once.
5-13
(13 is an exponet)
times 55
(5 is an exponet)
times 25
(5 is an exponet)

2^5/5^8

Step-by-step explanation: This is a fraction. You are going to add the exponents then multiply it by 2^5 (^ indicates that this is an exponent) so it'll look like this.

5^-13+5 * 2^5

Then when you get your answer which should be 5^-8, you are going to turn it into a fraction which should look like this.

5^8/2^5

Or the other way around
