### Solution:

First rewrite as an equation

Utilizing the definition of a logarithm, rewrite in exponential form. if $b$ is not equal to $1$ and both $x$ and $b$ are positive real numbers.
Here the ${\mathit{log}}_{\left(x\right)}=y$ is equivalent to

In the equation, construct equivalent expressions with the same bases.

The two expressions can only be equivalent since their bases are the same if their exponents are also the same.

$x$ equals $2$ is the variable.
