Pre-Calc Logarithms other than base 10 Mr. Mui 2 pages

To convert from one base to another, this is the rule:

                log[a]x
     log[b]x = ---------
                log[a]b

For example, to convert from base 10 to base 2, we would say:

                log[10]x
     log[2]x = ----------
                log[10]2
