    1) Find the derivative of

    and

    2) Calculate the derivative.
    For (1), Its y=(x^4)^x Or x^{(4^x)} ?
    For (2), Use this: if f is a differentiable y=tanh(f(x)), then y'=sech^2(f(x)) f'(x).

    And who told you they were answers!?
    I asked you to specify your function. It is not an answer!
    for (2) I gave you a formula to solve your problem.
    there is no final answers in my #1 post in this thread.
