Simplify (5^-2)^4 please and thank you

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.

Well if you have 20 bats you probably want 20 balls? you don’t have enough context to answer the question.
