To simplify the expression \( 5^{-2} \times 5^{5} \), we can use the rule of exponents that states \( a^m \times a^n = a^{m+n} \).
Applying this rule here:
\[ 5^{-2} \times 5^{5} = 5^{-2 + 5} = 5^{3} \]
So the equivalent expression is \( 5^{3} \).
The correct answer is \( 5, \text{ cubed } (5^{3}) \).
