The question asks for an equivalent statement to $y = \log_5 x$.

To convert a logarithmic equation into its exponential form, we can use the definition of logarithms:

$y = \log_b x \quad \text{means} \quad b^y = x$

For $y = \log_5 x$, this means:

$5^y = x$

So, the correct equivalent statement is:

$x = 5^y$

This corresponds to the last option in the list: $x = 5^y$.
