Question

What is (-m)^-3n if m=2 and n=-24?

Please explain on a low level for me instead of just giving me the answer.

Answer 1

n(-m)⁻³

remember order of operations and

`x^(-m)= (1)/(x^m)` so
simplify the exponent first


`(-m)^(-3)= (1)/((-m)^3)= (1)/(-m^3)`
now multiply by n

`(n)/(-m^3)`

n=-24
m=2



`(-24)/(-2^3)`

`(-24)/(-8)`
3

the result is 3
