Regina Castaneda · Answer 1

So if you have the negative then you just have it over one so 2^-2 means

(1 / (2^2)) = 2^-2 so

-5^-2=1 / (-5^2) = 1/25

Reilly Bird · Answer 2

-5^-2

taking something to the power of - 2 is basically saying to take it to the power of 2, and then inverse it

-5^2 = 25

inverse of 25 = 1/25

-5^-2 = 1/25, or 0.04
