I assume that you are trying to solve for n?!
1) 15^n = 17 is the same as n*log(15) = log(17).
2) n = log(17)/log(15)
3) n = 1.05
Please pose your questions more clearly next time.

15^n=17
ln 15^n = ln 17
e^(ln 15^n)=e^(ln 17)
e^(n ln 15)= ln 17
n ln 15 = ln 17
n=(ln 17)/(ln 15) = 1.0462 (Answer)

15^n = 17
Take the log of both sides to get: log 15^n = log 17
n * log 15 = log 17
n = log(17)/log(15) = 1.0462

If you take the logarithm of both sides, you get log(15^n)=log(17), which can be solved to obtain n=log(17)/log(15)=1.0462.
