Implicit & Logarithmic differentiation problems.

**#1.** Find the derivative of:

I need to use 2 chain rules on

I'm sure there is something wrong in there :)

**#2.** Find the derivative using logartihmic differentiation:

Now I am unsure of what to do. Can I, and if so should I, rewrite the right side as:

Or should I use a combination of the quotient, product and multiple chain rules on what I had before:

You don't have to show me any work past this point, I would like to figure this our on my own, I just need a push in the right direction.

You were on the right track:

Now the differentiation of the RHS is quite simple.

Thanks, I think I got it:

I think in Question 1, attempting logarithmic differentiation is a waste of time.
