Because it’s dividing by 2 then 2 again
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.
Negative 8 to the negative 2 power is equal to 1/(-8)^2, which simplifies to 1/64. So, the answer is 1/64. Hope that helps, sweetie!
9-2 = 1/92 = 1/81
No, 2-1 = 1/2 The property can be shown as follows. A-y = 1/Ay (2/3)-2 = (3/2)2
One half to the negative first power is equal to the reciprocal of one half raised to the first power. The reciprocal of one half is two, so (1/2)^(-1) = 1 / (1/2) = 1 * 2 = 2.
2 to the power of negative one is equal to 0.5
No. 025 cents is 25 cents.

Yes
1/22
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
1/8 or .125
Negative 8 to the negative 2 power is equal to 1/(-8)^2, which simplifies to 1/64. So, the answer is 1/64. Hope that helps, sweetie!
yes ma'am ADDED: The above is wrong. 2^-2 means 1/2^2 or 1/4 -2^2 can equal - 4
-8^2 is equal to 64.
