f(x)= (lnx)/(1-e^x) Its got me stumped, I understand the basics of deriving the simpler versions of these. lnx=1/x but, I am having problems with coming up with the solution for this.

You have to apply the Quotient Rule: $\displaystyle \left[ {\frac{{f(x)}} {{g(x)}}} \right]' = \frac{{f'(x) \cdot g(x) - f(x) \cdot g'(x)}} {{g^2 (x)}}.$
