The answer is 1/2!

-2 ^ (-3) = 1 / (-2)^3 = -1/8

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

2 to the negative 6th power as a fraction = 1/64

9 to negative 2 = 1/9 to plus 2 = 1/81

2-1 x 2-2 = 2-1 + -2 = 2-3 = 1/8, or one eighth.

That is the definition of negative powers.

-2 to the first power = -2^1. -2^1 = -2*1. -2*1 = -2. The answer is negative two.

2-1 = 1/(21) = 1/2 = 0.5

2-2 = 1/4

1/22

A negative exponent is 1 over the base to the power of the absolute value of the exponent. For example 2 to the power of -1 is 1/2, 2 to the power of -2 is 1/4, or (1/2) squared, and 2 to the power of -3 is 1/8, or (1/2) cubed.

for expanding negative powers of a number you take 1 divided by the number to the positive power and expand. For example 2 to the -1 power is 1 divided by 2 to the + 1 power = 1/2 2 to the -3 power is 1 divided by 2 tot he + 3 power = 1/8 this is called inverse

the answer= 1/8

1/2, or .5When you raise a number to a negative power, you are dividing one by that number to the positive version of that power. For example, 5^-6 = 1/(5^6).So, 2^-1 = 1/(2^1), or 1/2, which = .5

It is: 3-1*3-2 = 1/27
