$\log_{0.2} (25) = - 2$

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

${0.2}^{- 2} = 25$

The left side $25$ is equal to the right side $25$ , which means that the given statement is always true.
