Thread: solving logarithm

I can solve basic logarithms but I can't figure out how to solve this one. I tried reviewing the rules of logarithm and I thought that I should start solving from right to left but still can't get a valid answer.




Find z.

The selections are a)0 b)1 c)2 d)3


Any ideas ?

Well if you want all that equal to 0 you need the last log to be log of 1.
So log3(9)=2 so you was logz(2)=1
does that help?
