I am sorry for wasting your time with elementary mathematics but I can not complete my homework. (excuse the clutter, for I do not know how to use Latex) cube root ( -125 m^-4 n^5 ) I fully simplify this to: -5n/m * cube root (n^2 / m ) The answer is incorrect, wtf am I missing?

First I'd like to say that I'm getting back into college after several years out in the job market. Unfortunately, I need to complete several more upper division math courses before I can complete my CS degree. Before I go back and start taking my classes again, I've been trying to self-study...
