Logarithm change base formula

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.

MATHEMATICS 0110A CHANGE OF BASE Suppose that we have

Let y = logb a. Then we know that this means that by = a. We can take logarithms to base c
