1. The problem statement, all variables and given/known data Assume the notation log(a, x) implies log base a of x, where a is a constant (since I don't know LaTeX). PROBLEM: If y = [log(a, x^2)]^2, determine y'. 2. Relevant equations Chain Rule and Logarithmic Differentiation 3. The attempt at a solution y' = 2(log(a, x^2)) * (1/[(x^2)lna]) * (2x) = (8log(a,x))/(xlna) Is this the correct approach and solution?
