How would you find the derivative of (3/(x^34)) by using the chain rule?

Let u(v) = 3/v and v(x) = x^3 4
The original function is u[v(x)]
du[v(x)]/dx = du/dv * dv/dx
= 3/v^2 * (3x^2)
= x^2/(x^3 4)^2

Please help. Applying the chain rule, how do I find the derivative of f(x)=In(e^xe^x) (x>0) and then using this answer use the quotient rule to find the second derivative. I cannot do this so any answer greatly appreciated.
