Hello, Maskawisewin!

I've been given this problem and I've been working on it for a week on and off

trying to figure out how to simplify it so it looks a bit cleaner.

I can get the derivative without issue (I hope it's right),

but my simplifying bag-of-tricks is not as developed as it should be.

Original question -- Use logarithmic differentiation to find the derivative:

. .

Is my instructor just trying to make me go mad or am I missing something?

. . It depends . . . Is that your answer or the book's answer?

Trying to learn when to stop simplifying is difficult at times.

If that isanswer, good work!your

. . I got the same answer.

If that is the book's answer (and I assume you didn't get it),

. . I need to see your work to make any comments.
