Laws of Logarithms

Without using a calculator use the change of base rule to evaluate

1. a) log(subscript8)32(hint use base 2)
=log(subscript2 32)/log(subscript2 8) = 5/3

b) log(subscript36)1296. This one doesnt even give you a hint, so how do you know which base to use? Does it have to be a factor of 36 and 1296? Cause for the first one I could have used base four instead of 2 then.
