9 to the negative 9th power is 2.58117479e-9
9-2 = 1/92 = 1/81
5.3965953e-16
Negative 9 to the negative 2nd power (-9-2) = 0.012345679 (repeating).
1/36
-3^2 = 9 -(3^2) = -9
-32 = -(32) = -9 (-3)2 = 9 The difference is 9 - (-9) = 18.
3-2 = 9
-3 to the 2nd power is -3 x -3 = +9 ( negative x negative = positive)
(-3)^2 =9 but -3^2 = -9
(-2/3)^2 = 4/9
30 + 3-2 = 10/9
9 to the negative 9th power is 2.58117479e-9
9-2 = 1/92 = 1/81
5.3965953e-16
Negative 9 to the negative 2nd power (-9-2) = 0.012345679 (repeating).
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
