How to change the base of a log

The logarithm change of base formula is given by: log b (x) = log a (x) / log a (b), where a, b, and x are positive real numbers and a, b are both not equal to 1. This formula helps us to solve

Using the Change-of-Base Formula for Logarithms

The change of base formula says log\(_b\) a = [log\(_c\) a] / [log\(_c\) b]. It means to change the base of a logarithm log\(_b\) a, we just use division [log a] / [log b] where these logarithms can have any (same) positive number as a base.
