This algebra 2 video tutorial provides a basic introduction of logarithms. It explains the process of evaluating logarithmic expressions without a calculator. Examples

\log _2(x+1)=\log _3(27) \ln (x+2)-\ln (x+1)=1 \ln (x)+\ln (x-1)=\ln (3x+12) 4+\log _3(7x)=10 \ln (10)-\ln (7-x)=\ln (x) \log _2(x^2-6x)=3+\log _2(1-x)
