1. The problem statement, all variables and given/known data g(t) = 4ln(5ln(4t)) 2. Relevant equations What is the derivative of g(t)? 3. The attempt at a solution I have tried to use the chain rule in many different ways, and still can't come up with the correct answer. Anybody care to walk me through this? Is the derivative of ln(4t) still 1/t?
