What is the change of base formula by definition.
"Change of Base Formula. A formula that allows you to rewrite a logarithm in terms of logs written with another base. This is especially helpful when using a calculator to evaluate a log to any base other than 10 or e. Assume that x, a, and b are all positive"
Example: Logb x = Loga x/Loga b Pick a new base and the formula says it is equal to the log of the number in the new base divided by the log of theE old base in the new base.
Solution: Change tobase 10 and use your calculator. Now use your calculator and round to hundredths.
