Step 2.1

Rewrite $\log (x) = 0$ in exponential form using the definition of a logarithm. If $x$ and $b$ are positive real numbers and $b \neq 1$ , then $\log_{b} (x) = y$ is equivalent to $b^{y} = x$ .

$10^{0} = x$

Step 2.2

Solve for $x$ .

Step 2.2.1

Rewrite the equation as $x = 10^{0}$ .

$x = 10^{0}$

Step 2.2.2

Anything raised to $0$ is $1$ .

$x = 1$
