1. The problem statement, all variables and given/known data This is the problem and my attempt. I understand that I can take ln of both sides. However, I am trying to see if it is at all possible to arrive at the correct derivative without taking ln of both sides. I am under the impression that an alternative to taking ln of both sides is to use the power rule on terms with a variable as the exponent. So using this approach to this function, what am I doing wrong? If all is correct so far, I can not see what step to take next.
