No Actually... x^(-y) is equal to 1/x^y. 2^(-2) is equal to 1/2^2 which is equal to 1/4 or 0.25.
A number to a negative power is equal to One divided by number to its positive power. So, x^-2 is equal to 1/x2.
16 -2-4 = 0.0625
2 to the 3rd power = 8
2 to the 3rd power = 2 * 2 * 2 = 8
2^3 = 2*2*2 or 8
