Write each expression in terms of common logarithms, and then give a calculator approximation (correct to four decimal places). log8 313 exact value
$$log_8 (313)=\frac{log(313)}{log(8)}$$
$${\frac{{log}_{10}\left({\mathtt{313}}\right)}{{log}_{10}\left({\mathtt{8}}\right)}} = {\mathtt{2.763\: \!339\: \!615\: \!644\: \!206\: \!2}}$$
