Change the logarithm to base $10$ applying the change of base formula for logarithms: $\log_b(a)=\frac{\log_{10}(a)}{\log_{10}(b)}$. Since $\log_{10}(b)=\log(b)$, we don't need to write the $10$ as base
$\frac{\log \left(9\right)}{\log \left(3\right)}$
2
Evaluating the logarithm of base $10$ of $3$
$\frac{\log \left(9\right)}{0.4771}$
Final answer to the problem
$\frac{\log \left(9\right)}{0.4771}$
