9 to the negative 9th power is 2.58117479e-9
Whenever you see a negative exponent (the negative 2nd power), take the reciprocal of the answer (put one over it):x-y = 1/xySo:9-2 = 1/92 = 1/81 = 0.01234567901
0.000244140625
5.3965953e-16
5 over 8 to the negative 2nd power equals 2.56
The answer is 1. X=(3)^2 * (3)^-2 X=(3)^2 * 1/(3)^2 X=9 * 1/9 X=9/9 X=1
