解答ステップ

28271.59 (1 + 0.065)^{- 3}

指数の規則を適用する:

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

= 28271.59 \cdot \frac{1}{( 1 + 0.065 ) ^{3}}

数を足す:

1 + 0.065 = 1.065

= 28271.59 \cdot \frac{1}{1.06 5 ^{3}}

分数を乗じる:

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

= \frac{1 \cdot 28271.59}{1.06 5 ^{3}}

数を乗じる:

1 \cdot 28271.59 = 28271.59

= \frac{28271.59}{1.06 5 ^{3}}

1.06 5^{3} = 1.20794 \dots

= \frac{28271.59}{1.20794 \dots}

数を割る:

\frac{28271.59}{1.20794 \dots} = 23404.61010 \dots

= 23404.61010 \dots
