Answer:
1/390625
Explanation:
(5^-2)^4
=(1/(5^2))^4
=(1/25)^4
=(1^4)/(25^4)
=1/390,625
When there is a negative in the exponent, find the reciprocal of the number. In this problem, 5^-2 became 1/(5^2) to rid of the negative in the exponent. 1/(5^2) is simplified to 1/25 which was then to the power of 4 to result in 1/390625.
