簡約

3.12 \cdot 2.6 \cdot 1 0^{- 2}

0.08112

解答ステップ

3.12 \cdot 2.6 \cdot 1 0^{- 2}

数を乗じる:

3.12 \cdot 2.6 = 8.112

= 8.112 \cdot 1 0^{- 2}

= 1 0^{- 2} \cdot 8.112

指数の規則を適用する:

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

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

= \frac{1}{1 0 ^{2}} \cdot 8.112

1 0^{2} = 100

= \frac{1}{100} \cdot 8.112

\frac{1}{100} \cdot 8.112 = \frac{8.112}{100}

= \frac{8.112}{100}

数を割る:

\frac{8.112}{100} = 0.08112

= 0.08112
