$x = 1000$ $x = 1000$

Explanation:

Remember the definition of logarithm, that is
If ${log}_{b} (a) = c$ $log_b(a) = c$ is true, then $a = b^{c}$ $a = b^c$ , and if no base is explicitly put we always assume it's the base 10 (unless it's written as $ln x$ $lnx$ in which case the base is the irrational number $e$ $e$ )

$log x = 3 \to x = 10^{3} \to x = 1000$ $logx = 3 rarr x = 10^3 rarr x = 1000$
