simplify-2(0.5)^{-2}

Solution

simplify

- 2 (0.5)^{- 2}

Solution

- 8

Solution steps

- 2 \cdot 0. 5^{- 2}

Apply exponent rule:

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

0. 5^{- 2} = \frac{1}{0. 5 ^{2}}

= - 2 \cdot \frac{1}{0. 5 ^{2}}

0. 5^{2} = 0.25

= - 2 \cdot \frac{1}{0.25}

Divide the numbers:

\frac{1}{0.25} = 4

= - 2 \cdot 4

Multiply the numbers:

- 2 \cdot 4 = - 8

= - 8
