Well if log_{b}(5)=.9 and log_{b}b=1 then .9(1)=.9

If I had the function R=2.3log(A+3000)-5.1 and I wanted solve for A in terms of R, would A=10^{((R/2.3)-5.1))}-3000 be correct?

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 ...
