Homework Statement
Differentiate:
f(x) = e^(x^3)
Homework Equations
The Attempt at a Solution
lnf(x) = ln(e) + 3ln(x)
1 / f(x) f'(x) = 1 + 3x^2 / x^3
f'(x) = ( e^(x^3) * 3X^2 ) / x^3
However, my book says the answer is 3x^2*e^(x^3).
Any help would be greatly appreciated! I've been stuck on this question for ages!
