How do you simplify (-5q2p)3?

Answer 1

minus a minus is plus, so it's -8 + 3, which is 3 - 8, or -5

Answer 2

If the '3' to the right is intended to be a 'power/index' number. then

(-5q^(2)p)^(3) = -125q^(6)p^(3)

It '3' is intended to be a coefficient, then it is in the wrong place, and should be written to the left of the brackets.

3(-5q^(2)p) = -15q^(2)p.
