The change-of-base property shows that we could use any base a to rewrite the logarithm, but if we want to use our calculator to evaluate the logarithm we need to use base 10 or base e

This leaflet gives this formula and shows how to use it. A formula for change of base. Suppose we want to calculate a logarithm to base 2. The formula states.
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.
Let y = logb a. Then we know that this means that by = a. We can take logarithms to base c
Enter the values of a and b that you found. The program graphs two logarithmic functions with bases you entered as thick lines on top of the original graph. If
Therefore x > 0 and x = 1 so x can be the base of logarithms. We get: 1 loga x. = logxa = log2 a log2 x. (f) Again
