MATHEMATICS 0110A CHANGE OF BASE Suppose that we have

So we get the following rule: Change of Base Formula: logb a = logc a logc b. Example 1. Express log3 10 using natural logarithms. log3 10 = ln 10 ln 3.

Appendix N: Derivation of the Logarithm Change of Base Formula

We set out to prove the logarithm change of base formula: logb x = loga x loga b. To do so we let y = logb x and apply these as exponents on the base.


Change-of-Base Formula. For any logarithmic bases a and b and
