simplify 2(1/2)^{-2}

Solution

simplify

2 (\frac{1}{2})^{- 2}

Solution

8

Solution steps

2 (\frac{1}{2})^{- 2}

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

(\frac{1}{2})^{- 2} = \frac{1}{( \frac{1}{2} ) ^{2}}

= 2 \cdot \frac{1}{( \frac{1}{2} ) ^{2}}

(\frac{1}{2})^{2} = \frac{1}{4}

= 2 \cdot \frac{1}{\frac{1}{4}}

\frac{1}{\frac{1}{4}} = 4

= 2 \cdot 4

Multiply the numbers:

2 \cdot 4 = 8

= 8
