Solve for x 72 = log of x

Rewrite the equation as ${\displaystyle \log \left(x\right)=72}$.

Rewrite ${\displaystyle \log \left(x\right)=72}$ in exponential form using the definition of a logarithm. If ${\displaystyle x}$ and ${\displaystyle b}$ are positive real numbers and ${\displaystyle b\ne 1}$, then ${\displaystyle {\log }_b\left(x\right)=y}$ is equivalent to ${\displaystyle b^y=x}$.

Rewrite the equation as ${\displaystyle x={10}^{72}}$.
