10^6 = 1000000 (6 zeroes)
10^5 = 100000
10^4= 10000
10^3 = 1000
10^2 = 100
10^1 = 10
10^0 = 1
10^(-1) = 0.1 = 1/10
10^(-2)= 0.01 = 1/100
It's the same with fives.
5^2 = 25
5^1 = 5
5^0 = 1
5^(-1) = 1/5
5^(-2) = 1/25
There's your answer. 1/25. Study this answer carefully, and look up the formula for dividing two terms with exponents (you subtract the exponents). This will help you answer further questions of this type. Hope this helps.

The negative sign means take the inverse of 5^2.
5^2 = 25 ---> now take the inverse ---> 1/25 ---> 0.04
