`y=log x` and `y=10` set both equation equal to each othr \[\huge\rm 10=\log x\]
then rewrite this log equation to in an exponential form
\[\large\rm \log_\color{Red}{b} \color{orange}{x} =\color{blue}{y} \]
\[\large\rm \color{orange}{x}= \color{red}{b}^\color{blue}{y}\]

Answer 2

\[\log = \log_{10}\]
