Properties of logarithmic functions

I have a series of problems that state: given that log b (2)=.39, log b (3)=.61 and log b (5)=.9, find the following for logs, do no try to find "b" Then there are easy ones to solve using multiplication and division properties, but there is one I'm not sure about. b log b (5) Can that go any furthe...
