The answer to your question is:
Step-by-step explanation:
Given
25² = 625
Show that
5⁻⁴ = [tex]\frac{1}{625}[/tex]
Process
Find the prime factors of 25
25 5
5 5
1
Then 25 = 5²
Substitution
(5²)² = 625
(5)⁴ = 625
Get the inverse
(5⁴) ⁻¹ = 625⁻¹
But negative powers are not allowed, then,
[tex]5^{-4} = \frac{1}{5^{4} } = \frac{1}{625}[/tex]
