$\log_{1000} (x) = \frac{1}{3}$

Step 1

Rewrite $\log_{1000} (x) = \frac{1}{3}$ 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 $b^{y} = x$ .

$1000^{\frac{1}{3}} = x$

Step 2

Solve for $x$ .
