Answer:
25
Step-by-step explanation:
Given the indicinal equation
5^-1/5^-3
According to one of the law of indices, if a, b, m and n are integers then;
a^m/a^n = a^(m-n)
When the base are equal, the powers will be subtracted.
Applying this formula to the given expression
= 5^{-1-(-3)}
= 5^(-1+3)
= 5^2
= 25
Therefore the answer is 25
the answer is c
