Answer
$(g)$
Work Step by Step
We use the definition of logarithm to rewrite a logarithmic equation as an equivalent exponential equation or the other way around:
$m=\log_{a}x$ is equivalent to $a^{m}=x.$
$\log_{5}25$ is the exponent $(2)$ to which $5$ must be raised in order to get $25.$
$5^{2}=25 \Leftrightarrow \log_{5}25=2$
