1. The problem statement, all variables and given/known data Differentiate: f(x) = e^(x^3) 2. Relevant equations 3. 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!
