This tutorial shows you how to take a logarithm and rewrite it as a common logarithm. Using logarithm change of base formula log_ b x frac log_ d x log_ d b 2 log_ 4 29 2 times frac log_ 10 29 log_ 10 4 2 log_ 4 29 2 x 243 486. Logarithm Change of Base Rule Logarithm change of base rule.
The change of base formula allows us to convert a logarithm from one base to another.
To do that you need to use the Change of Base Formula. Use the change of base formula to find log base 5 of 100 to the nearest thousandth. For example 2 3 8. You da real mvps.
