    Since we have to derivative the y, aka function of x and we have to derivative w³ln(20w) in respect of x. Apparently there is no x variable. Since we have to derivative in respect of x, we have to treat w as constant and hence the answer is zero.

    i know that the derivative for f is 3w^2 but i have problems deriving natural logs

    natural logs are easy, the derivative of a natural log is 1/(whatever was in the brackets)
