Question

$$(2^{-7}\div2^{-8})\times2^{2}$$

Evaluate

$8$

Solution Steps

To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent. Subtract $-8$ from $-7$ to get $1$.

$$2^{1}\times 2^{2}$$

To multiply powers of the same base, add their exponents. Add $1$ and $2$ to get $3$.

$$2^{3}$$

Calculate $2$ to the power of $3$ and get $8$.

$$8$$

Factor

$2^{3}$
