400 e^{- 0.0244 (40)}

150.72613 \dots

解答ステップ

400 e^{- 0.0244 (40)}

指数の規則を適用する:

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

= 400 \cdot \frac{1}{e ^{40 \cdot 0.0244}}

数を乗じる:

0.0244 \cdot 40 = 0.976

= 400 \cdot \frac{1}{e ^{0.976}}

分数を乗じる:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{1 \cdot 400}{e ^{0.976}}

数を乗じる:

1 \cdot 400 = 400

= \frac{400}{e ^{0.976}}

e^{0.976} = 2.65381 \dots

= \frac{400}{2.65381 \dots}

数を割る:

\frac{400}{2.65381 \dots} = 150.72613 \dots

= 150.72613 \dots
