How to Evaluate Logarithms? (+FREE Worksheet!)
Open Logarithm Calculator in full screen Open the Logarithm Calculator in full screen → Evaluating logarithms – Example 1: Evaluate: \(log_{2}{16}\) Solution: Rewrite \(16\) in power base form: \(16=2^4\), then: \(log_{2}{16}=log_{2}{(2^4)}\) Use log rule: \(log_{a}{x^b}=b log_{a}{x}\), then: \(log_{2}{(2^4)}=4log_{2}{2}\) Use log rule: \(log_{a}{a}=1\), then: \( 4log_{2}{2}=4\times1=4\) The Absolute Best Books to Ace Pre-Algebra to Algebra II […]
