$x = {log}_{10} 30 \approx 1.477$ $x=log_10 30 ~~ 1.477$

${log}_{b} p = q$ $log_b p = q$ is equivalent to $b^{q} = p$ $b^q=p$

Therefore
$10^{x} = 30$ $10^x=30$ is equivalent to ${log}_{10} 30 = x$ $log_10 30 = x$

${log}_{10} 30$ $log_10 30$ can be evaluated using a calculator as $\approx 1.477$ $~~1.477$
