Answer
$\frac{1}{4}$
Work Step by Step
When an exponential expression has a negative exponent, change the position of the base (from the numerator to the denominator, or vise-versa) and make the exponent positive.
$$2^{-3}\times2$$
$$=\frac{1}{2^{3}}\times2$$
$$=\frac{1}{8}\times\frac{2}{1}$$
$$=\frac{1}{4}$$
