Question 1034404
(x-1)/ln3x  please solve this derivative
===========
Finding the derivative is not solving.
---
f(x) = (x-1)/ln(3x) = (x-1)*(ln(3x))^-1
f'(x) = {{{(ln(3x))^-1 + (x-1)*(-1)*(ln(3x))^-2*(1/3x)*3}}} -- product rule
= {{{(ln(3x))^-1 - ((x-1)/x)*(ln(3x))^-2}}}
--------
Rearrangement and "simplification" is possible.
