y=x^((sin^(3)*(3x)*cosx)). Find the derivative using logarithmic differentiation.

Rachel, you definitely used grouping symbols to make the definition of y clear. Is the factor cos(x) really supposed to be part of the exponent. Please take a look at this graph and confirm that it is f1(x) rather than f2(x) that is the definition for y. desmos.com/calculator/bnwvpc80bo

Cos(x) is part of the exponent

Here is the problem. Your notation is still not clear. If 3x is a parameter to the sin function there should not be a multiplication symbol between the exponent of 3 and the (3x). If you want to get help with this problem you are going to have to ensure that f1(x) at the Desmos graph is the correct interpretation.
