簡約

(6.5 \cdot 1 0^{- 9}) \cdot 25

0.0000001625

解答ステップ

(6.5 \cdot 1 0^{- 9}) \cdot 25

1 0^{- 9} = \frac{1}{1000000000}

= 6.5 \cdot \frac{1}{1000000000} \cdot 25

6.5 \cdot \frac{1}{1000000000} = \frac{6.5}{1000000000}

= \frac{6.5}{1000000000} \cdot 25

数を割る:

\frac{6.5}{1000000000} = 0.0000000065

= 0.0000000065 \cdot 25

数を乗じる:

0.0000000065 \cdot 25 = 0.0000001625

= 0.0000001625
