\textbf{To check:}

\mathsf{log_4{64}\;is\;rational\;or\;irrational}

\textbf{Solution:}

\textsf{Consider,}

\mathsf{log_4{64}}

\mathsf{=log_4{4}^3}

\textsf{Using power rule of logarithm,}

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

\mathsf{=3\,log_4{4}}

\mathsf{=3(1)}

\mathsf{=3\;which\;is\;rational}

\therefore\mathsf{log_4{64}\;is\;rational}
