In the process of working on a problem with logarithmic and exponential functions I came across a deceptively simple function: d/dx ((2x)4x ) whose step-wise solution eludes me. I have been given the answer :                           4 (2x + 1) x4x  (1+ ln 2x) but the process steps still elude me. There similar forms of this problem in the assignment so its solution is important me. Would you please help me to understand the process?
