簡約

(3.8 \cdot 1 0^{- 6}) \cdot 0.012

0.0000000456

解答ステップ

(3.8 \cdot 1 0^{- 6}) \cdot 0.012

1 0^{- 6} = \frac{1}{1000000}

= 3.8 \cdot \frac{1}{1000000} \cdot 0.012

3.8 \cdot \frac{1}{1000000} = \frac{3.8}{1000000}

= \frac{3.8}{1000000} \cdot 0.012

数を割る:

\frac{3.8}{1000000} = 0.0000038

= 0.0000038 \cdot 0.012

数を乗じる:

0.0000038 \cdot 0.012 = 0.0000000456

= 0.0000000456
