簡約 2.710^{-4}(1+0.004*(0-20))

解

簡約

2.7 \cdot 1 0^{- 4} \cdot (1 + 0.004 \cdot (0 - 20))

0.0002484

解答ステップ

2.7 \cdot 1 0^{- 4} (1 + 0.004 (0 - 20))

1 0^{- 4} = \frac{1}{10000}

= 2.7 \cdot \frac{1}{10000} (1 + 0.004 (0 - 20))

1 + 0.004 (0 - 20) = 0.92

= 2.7 \cdot \frac{1}{10000} \cdot 0.92

数を乗じる:

2.7 \cdot 0.92 = 2.484

= 2.484 \cdot \frac{1}{10000}

= \frac{1}{10000} \cdot 2.484

\frac{1}{10000} \cdot 2.484 = \frac{2.484}{10000}

= \frac{2.484}{10000}

数を割る:

\frac{2.484}{10000} = 0.0002484

= 0.0002484
