Basically don't be afraid of the e to the power of ln it essentially cancels out to give you 2(3x+y) if I am not wrong. And hence we just have to differentiate the equation I mentioned above

There is an error though, it should be 2pi(3x+y) forgotten about the pie and every answer below that is expanded from the above equation will have a pi in it ! Sorry !

You can try typing it into your calculator like e to the power of a certain number let's say 9. So like e^ln(9). It will then show the number 9 which indicates that the e^ln cancels out each other !
