\underline{\textsf{To find:}}

\textsf{Expansion of}

\mathsf{log\,18}

\underline{\textsf{Solution:}}

\textsf{Consider,}

\mathsf{log\,18}

\mathsf{=log(2{\times}9)}

\textsf{Using product rule of logarithm}

\boxed{\mathsf{log_aMN=log_aM+log_aN}}

\mathsf{=log\,2+log\,9}

\mathsf{=log\,2+log\,3^2}

\textsf{Using power rule of logarithm}

\boxed{\mathsf{log_aM^n=n\;log_aM}}

\mathsf{=log\,2+2\;log\,3}

\implies\boxed{\mathsf{log\,18=log\,2+2\;log\,3}}
