# Question #3beb0

Aug 7, 2017

$\frac{1}{4}$

#### Explanation:

Simplifying the factors of each individual term will help make this question much easier

${2}^{0} = 1$

$- {2}^{-} \frac{1}{2} = - \frac{1}{2 \cdot 2} = - \frac{1}{4}$

$- 2 \cdot {2}^{-} 2 = - 2 \cdot \frac{1}{2} ^ 2 = - \frac{1}{2}$

Combining them together, we get

$1 - \frac{1}{4} - \frac{1}{2}$

$= \frac{1}{4}$
