    Natural log of a sum? (not sum of natural logs)

    Homework Statement Find the derivative of y = x^2 + x^(2x)The Attempt at a Solution By looking at the equation I think I need to use implicit differentiation + natural logs. But I can't do anything with: lny = ln(x^2 + x^(2x)) So I assume I'm wrong.. Any help??

    Finding the derivative of an unknowable inverse function

    Homework Statement The function f(x) has an inverse function, g(x). Find g'(5). Homework Equations f(x) = x^5 + 2x^2 + 2xThe Attempt at a Solution I don't see how I can possibly find the inverse of this function. So I opted to use the derivative rule for inverses. f'(x) = 5x^4 + 4x + 2 5...
