Complicated problem on test review. (Test tomorrow)

[airmonster]

Hey guys, so I'm working on a review for a test coming up tomorrow and I am having trouble with this problem, I don't have anything similar in my notes and don't even recall my teacher going over it.

I have parts a-c done, it's just part d that I don't know.

Thanks in advance guys!

Figured it out

Found out that it was because ln(ab)=ln(a)+ln(b)
I kinda figured it was something simple like that haha.
