解答ステップ

12070.8435 (1.045)^{- 7}

指数の規則を適用する:

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

= 12070.8435 \cdot \frac{1}{1.04 5 ^{7}}

分数を乗じる:

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

= \frac{1 \cdot 12070.8435}{1.04 5 ^{7}}

数を乗じる:

1 \cdot 12070.8435 = 12070.8435

= \frac{12070.8435}{1.04 5 ^{7}}

1.04 5^{7} = 1.36086 \dots

= \frac{12070.8435}{1.36086 \dots}

数を割る:

\frac{12070.8435}{1.36086 \dots} = 8869.99931 \dots

= 8869.99931 \dots
