simplify 2(0.2)^{-2}

Solution

simplify

2 (0.2)^{- 2}

Solution

50

Solution steps

2 \cdot 0. 2^{- 2}

Apply exponent rule:

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

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

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

0. 2^{2} = 0.04

= 2 \cdot \frac{1}{0.04}

Divide the numbers:

\frac{1}{0.04} = 25

= 2 \cdot 25

Multiply the numbers:

2 \cdot 25 = 50

= 50
