680.18018 \dots

解答ステップ

680180180.18 \cdot 1 0^{- 6}

指数の規則を適用する:

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

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

= 680180180.18 \cdot \frac{1}{1 0 ^{6}}

1 0^{6} = 1000000

= 680180180.18 \cdot \frac{1}{1000000}

680180180.18 \cdot \frac{1}{1000000} = \frac{680180180.18}{1000000}

= \frac{680180180.18}{1000000}

数を割る:

\frac{680180180.18}{1000000} = 680.18018 \dots

= 680.18018 \dots
