    f'(x)=g'(x+g(a))*(1+0)=g'(x+g(a))

    lol this is one of those questions that looks too easy to be true, but I think that is the answer.

    if a is a constant, g(a) is a constant, so when you differentiate g(x+g(a)), then you just have the derivative of g: g'(x+g(a)), multiplied by the derivative of the inside, but: x'=1 g(a)=0, since g(a) is a constant, so all you have left is: g'(x+g(a))

    yes derivaivte of x is 1 and that of a constant is 0 so it seems right...
