Simplify the expression where possible.

(-5x^2)^3

(2 and 3 are exponents)

Isn't the answer -5x^6?
(6 is an exponent)

Because my schooling website says it's only partially right and I don't know what isn't right about it.

First we need to do (-5x^2), which would be -125x^2, -5 got squared and so did x, then we raise (-125x^2)^3, which would be -125x^6, you were just forgetting to do parentheses first :)

Oh! Thank you! Sometimes I can forget the smallest (but most important) details. :P

sleepyjess · Answer

Wait, -5^2 would be 125, not -125, so it's actually 125x^6

Ah, thanks again :)
