解

簡約

1.334 \cdot 1 0^{- 9} (\frac{0.4}{0.5})

\frac{667}{625000000000}

十進法表記

1.0672 E - 9

解答ステップ

1.334 \cdot 1 0^{- 9} (\frac{0.4}{0.5})

\frac{0.4}{0.5} = \frac{4}{5}

= 1.334 \cdot 1 0^{- 9} \cdot \frac{4}{5}

1.334 = \frac{667}{500}

= \frac{667}{500} \cdot 1 0^{- 9} \cdot \frac{4}{5}

指数の規則を適用する:

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

1 0^{- 9} = \frac{1}{1 0 ^{9}}

= \frac{667}{500} \cdot \frac{1}{1 0 ^{9}} \cdot \frac{4}{5}

1 0^{9} = 1000000000

= \frac{667}{500} \cdot \frac{1}{1000000000} \cdot \frac{4}{5}

\frac{667}{500} \cdot \frac{1}{1000000000} \cdot \frac{4}{5} = \frac{667}{625000000000}

= \frac{667}{625000000000}
