Concepts

Continuing the pattern $2^2 = 4$ , $2^1 = 2$ , $2^0 = 1$ by dividing
by 2 at each step gives $2^{-1} = 1/2$ and $2^{-2} = 1/4$ . Based on
this pattern, is $2^{-3}$ positive or negative, and what is its
value?

Positive; $2^{-3} = 1/8$ .

Negative; $2^{-3} = -8$ .

Negative; $2^{-3} = -1/8$ .

Positive; $2^{-3} = 8$ .
