簡約 0.5(8.8710^{-6})*0.12288

解

簡約

0.5 \cdot (8.87 \cdot 1 0^{- 6}) \cdot 0.12288

5.44973 E - 7

解答ステップ

0.5 (8.87 \cdot 1 0^{- 6}) \cdot 0.12288

数を乗じる:

0.5 \cdot 0.12288 = 0.06144

= 0.06144 \cdot 8.87 \cdot 1 0^{- 6}

= 1 0^{- 6} \cdot 0.06144 \cdot 8.87

数を乗じる:

0.06144 \cdot 8.87 = 0.5449728

= 1 0^{- 6} \cdot 0.5449728

指数の規則を適用する:

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

1 0^{- 6} = \frac{1}{1 0 ^{6}}

= \frac{1}{1 0 ^{6}} \cdot 0.5449728

1 0^{6} = 1000000

= \frac{1}{1000000} \cdot 0.5449728

\frac{1}{1000000} \cdot 0.5449728 = \frac{0.5449728}{1000000}

= \frac{0.5449728}{1000000}

数を割る:

\frac{0.5449728}{1000000} = 5.44973 E - 7

= 5.44973 E - 7
