Differentiate the function

  1. 1. The problem statement, all variables and given/known data

    If [tex] f(x) = \int_{x^2}^{3x} \sqrt{t^3 + x^3} dt [/tex] then find the expression for f'(x)

    2. Relevant equations

    3. The attempt at a solution

    Usually I would use the FTC, but since there the variable x occurs in the integrand, I don't know how to differentiate this. Any help?
