## 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.

## 6.2 Properties of Logarithms

The proofs of the Change of Base formulas are a result of the other properties studied in this section. If we start with bx logb(a) and use the Power Rule
