Changing log base formula

WebThe change-of-base formula can be used to evaluate a logarithm with any base. For any positive real numbers M, b, and n, where n ≠1 n ≠ 1 and b≠ 1 b ≠ 1, logbM =lognM lognb l o g b M = l o g n M l o g n b. It follows that the change-of-base formula can be used to rewrite a logarithm with any base as the quotient of common or natural logs.
