Answer:

1/5

Explanation:

Given the equation:

The given equation can be written as:

$\begin{gathered} (10^y)^2=5^2 \\ \implies10^y=5 \end{gathered}$

Raise both sides of the equation to an index of -1.

$\begin{gathered} (10^y)^(-1)=5^(-1) \\ \implies10^(-y)=(1)/(5) \end{gathered}$

The correct answer is 1/5.
