When you use the Change of Base Formula to change the base of a log function, all that is changed is the form of the function. Instead of being one logarithm with a given base, the function becomes a fraction formed by two logarithms with whatever is the new base. All of the functiona...

In order to evaluate logarithms with a base other than 10 or ee, we use the change-of-base formula to rewrite the logarithm as the quotient of logarithms of any other base; when using a calculator, we would change them to common or natural logs. To derive the change-of-base...
