$\log_b x = \dfrac {\log_a x} {\log_a b}$.
$\log_b x = \dfrac {\log_a x} {\log_a b}$. And actually, we don't even need a calculator to evaluate this top part. They have functions for log base e, which is a natural logarithm, and log base 10. That means, if we have a logarithm using a specific base, then we can turn this into an equivalent ratio or fraction of two.
