簡約 0.5(1-(0.46)/2)(1-0.46)^{2-2}

解

簡約

0.5 \cdot (1 - \frac{0.46}{2}) \cdot (1 - 0.46)^{2 - 2}

0.385

解答ステップ

0.5 (1 - \frac{0.46}{2}) (1 - 0.46)^{2 - 2}

1 - \frac{0.46}{2} = \frac{77}{100}

= 0.5 \cdot \frac{77}{100} (1 - 0.46)^{2 - 2}

数を引く:

2 - 2 = 0

= 0.5 \cdot \frac{77}{100} (1 - 0.46)^{0}

数を引く:

1 - 0.46 = 0.54

= 0.5 \cdot \frac{77}{100} \cdot 0.5 4^{0}

指数の規則を適用する:

a^{0} = 1, a \neq = 0

0.5 4^{0} = 1

= 0.5 \cdot \frac{77}{100} \cdot 1

数を乗じる:

0.5 \cdot 1 = 0.5

= 0.5 \cdot \frac{77}{100}

= \frac{77}{100} \cdot 0.5

\frac{77}{100} \cdot 0.5 = \frac{38.5}{100}

= \frac{38.5}{100}

数を割る:

\frac{38.5}{100} = 0.385

= 0.385
