Question

What is (-m)^-3n If m=3 and n=-25?

Answer 1

First, welcome to OpenStudy!

Is this the problem?\[(-m)^{-3n}\] or is it \[(-m)^{-3}n\]?

Answer 2

so i think this wann being

(-m)^-3 *n so than this mean that (-m)^-3 = 1/ (-m)^3 *n = n/(-m)^3

so if m=3 and n=-25 than this will be

- 25 - 25 25
------ = ------ = ----
(-3)^3 - 27 27

hope you will understand it and that this will help you

good luck
