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.
They are equal 2^4 and 4^2 both equal 16.
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
16
Answer #1:Negative one-half to the negative 4th power, ie -((1/2)-4) equals -16Answer #2:Negative one-half to the negative 4th power, ie (-1/2)-4 equals +16
3
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
They are equal 2^4 and 4^2 both equal 16.
1/8 or .125
yes ,it does equal 80
