Logarithm change of base rule intro (article) Khan Academy
Using the change of base formula, solve logarithm problems that initially incllude bases other than 10 or e. You can do a bit more simplification. The important properties of the log function are, for any base a>0. loga(bc)=logab+logac, so, for example. We can change any base to a different base any time we want.
Pick a new base and the formula says it is equal to the log of the number in the new base.
