X -2
same as saying
1/X2
------
-3 to the 2nd power is -3 x -3 = +9 ( negative x negative = positive)
3
The answer is 1. X=(3)^2 * (3)^-2 X=(3)^2 * 1/(3)^2 X=9 * 1/9 X=9/9 X=1
Not a great deal. Multiply it by itself and divide by 4. If x is imaginary, x2 is negative.
A negative power. When something is to the power of negative two, say X it would be 1/X. If something is to the power of negative 3, it would be.... etc
-3 to the 2nd power is -3 x -3 = +9 ( negative x negative = positive)
If you have an even power the sign of the number does not matter. (-x)4 * (-x)2 = x4*x2 = x6
3
The answer is 1. X=(3)^2 * (3)^-2 X=(3)^2 * 1/(3)^2 X=9 * 1/9 X=9/9 X=1
Not a great deal. Multiply it by itself and divide by 4. If x is imaginary, x2 is negative.
Negative 9 to the negative 2nd power (-9-2) = 0.012345679 (repeating).
A negative power. When something is to the power of negative two, say X it would be 1/X. If something is to the power of negative 3, it would be.... etc

5 over 8 to the negative 2nd power equals 2.56
6 to the negative 2nd means that it equals 1 over 6 to the negative 2nd.
1 divided by x to the third power equals x to the negative third. The derivative of x to the negative third is minus three x to the negative fourth.
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
