Well do you know what the chain rule is? quotient rule?

those will probably be pretty useful here.

Do you know how to take the derivitive of Cuberoot(x)?

or how about cuberoot(x^2)

if not those, how about the square root (x)

How do you re-write the cuberoot in exponent form? I think that's whats messing you up.
