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

$\frac{\log \left(4\right)}{\log \left(2\right)}$

Final answer to the problem

$\frac{\log \left(4\right)}{\log \left(2\right)}$
