The Change of base formula helps to rewrite the logarithm in terms of another base log Change of base formula is used in the evaluation of log and have another base than 10 LARGE log b x frac log d x log d b Solved Examples Example 1 Solve 2 begin array l log 4 29 end array Solution Given 2 Use the change of base formula to find log base 5 of 100 to the nearest thousandth. So the change of base formula is a useful formula, especially when you're going to use a calculator, because most calculators don't allow you to.

Change Of Base FormulaTo do this, we apply the change of base rule with b = 2 , a = 50 , and x = 10 . log 2 ( 50) = log 10 ( 50) log 10 ( 2) Change of base rule = log ( 50) log ( 2) Since log 10 ( x) = log ( x) We can now find the value using the calculator. log ( 50) log ( 2) ≈ 5.644. What is the change of base formula The change of base formula allows us to rewrite a logarithmic expression so that the new expression contains a different base We normally use this whenever we need to evaluate logarithmic values on calculators that make use of either log for the base of 10 or ln for the base of e
