what is change of base formula. The change of base formula allows us to convert a logarithm from one base to another. What this rule says in practical terms is that you can evaluate a non-standard-base log by converting it to the fraction of the form standard-base log of the argument divided by same-standard-base log of the non-standard-base.
In this example a was 5 b is 100 and the base that we switched it to is 10. This formula involves finding the ratios between the logarithms between the original argument and base. Button opens signup modal.

The change of base formula is a formula for expressing a logarithm in one base in terms of logarithms in other bases. The change of base formula is the formula that will give you the answer of a log with a different base by using only log calculations with a base of 10. This is called the Change of Base Formula. The Change-of-Base Formula is an instruction on how to rewrite or transform a given logarithmic expression as a ratio or fraction of two logarithm operations using any valid base.
