簡約

(5.2 \cdot 1 0^{- 6}) \cdot 0.42

0.000002184

解答ステップ

(5.2 \cdot 1 0^{- 6}) \cdot 0.42

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

= 5.2 \cdot \frac{1}{1000000} \cdot 0.42

5.2 \cdot \frac{1}{1000000} = \frac{5.2}{1000000}

= \frac{5.2}{1000000} \cdot 0.42

数を割る:

\frac{5.2}{1000000} = 0.0000052

= 0.0000052 \cdot 0.42

数を乗じる:

0.0000052 \cdot 0.42 = 0.000002184

= 0.000002184
