解

簡約

8.85 \cdot 1 0^{- 12} (4) (\frac{1}{6 \cdot 1 0 ^{7}} - \frac{1}{1 0 ^{7}})

\frac{59}{1 0 ^{20}} - \frac{177}{1 0 ^{19} \cdot 5}

十進法表記

0

解答ステップ

8.85 \cdot 1 0^{- 12} (4) (\frac{1}{6 \cdot 1 0 ^{7}} - \frac{1}{1 0 ^{7}})

規則を適用する:

(a) = a

(4) = 4

= 8.85 \cdot 1 0^{- 12} \cdot 4 (\frac{1}{6 \cdot 1 0 ^{7}} - \frac{1}{1 0 ^{7}})

数を乗じる:

8.85 \cdot 4 = 35.4

= 35.4 \cdot 1 0^{- 12} (\frac{1}{6 \cdot 1 0 ^{7}} - \frac{1}{1 0 ^{7}})

= 1 0^{- 12} \cdot 35.4 (\frac{1}{6 \cdot 1 0 ^{7}} - \frac{1}{1 0 ^{7}})

指数の規則を適用する:

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

1 0^{- 12} = \frac{1}{1 0 ^{12}}

= \frac{1}{1 0 ^{12}} \cdot 35.4 (\frac{1}{6 \cdot 1 0 ^{7}} - \frac{1}{1 0 ^{7}})

\frac{1}{1 0 ^{12}} \cdot 35.4 (\frac{1}{6 \cdot 1 0 ^{7}} - \frac{1}{1 0 ^{7}}) = \frac{35.4}{1 0 ^{12}} (\frac{1}{6 \cdot 1 0 ^{7}} - \frac{1}{1 0 ^{7}})

= \frac{35.4}{1 0 ^{12}} (\frac{1}{6 \cdot 1 0 ^{7}} - \frac{1}{1 0 ^{7}})

\frac{35.4}{1 0 ^{12}} = \frac{354}{10 \cdot 1 0 ^{12}}

= \frac{354}{10 \cdot 1 0 ^{12}} (\frac{1}{6 \cdot 1 0 ^{7}} - \frac{1}{1 0 ^{7}})

キャンセル

\frac{354}{10 \cdot 1 0 ^{12}} : \frac{177}{5 \cdot 1 0 ^{12}}

= \frac{177}{5 \cdot 1 0 ^{12}} (\frac{1}{6 \cdot 1 0 ^{7}} - \frac{1}{1 0 ^{7}})

拡張

\frac{177}{5 \cdot 1 0 ^{12}} (\frac{1}{6 \cdot 1 0 ^{7}} - \frac{1}{1 0 ^{7}}) : \frac{59}{1 0 ^{20}} - \frac{177}{1 0 ^{19} \cdot 5}

= \frac{59}{1 0 ^{20}} - \frac{177}{1 0 ^{19} \cdot 5}
