I got my recent test back and one of the questions was to find dy/dx of the following:

ln( )... Sorry i had trouble writing it out formaly but its ln of whats in the bracket.

I seemed to solved it but i just ended up with a HUGE long denominator and ended up getting 2 marks out of 5 soo i was wondering if someone would be kind enough to solve this with the steps soo i can see where i went wrong. There are soo many brackets im just lost trying to trace it back. Thanks would be appriciated
