Simplify the expression given bellow. : -5^-2
-5^-2taking something to the power of -2 is basically saying to take it to the power of 2, and then inverse it-5^2 = 25inverse of 25 = 1/25-5^-2 = 1/25, or 0.04
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
