Take each and every one of those things inside the parenthesis to the 3rd power...all of it, one at a time.

Right off you will see that B is incorrect because -4^3 is a negative number, not a positive one.

And when you take an exponent to another power, like$$(x ^{2})^{3}$$You mulitply the exponents to get x^6.  Does that help you?
