解答ステップ

1690 (\frac{( 1 + 0.07 ) ^{38} - 1}{0.07})

括弧を削除する:

(a) = a

= 1690 \cdot \frac{( 1 + 0.07 ) ^{38} - 1}{0.07}

(1 + 0.07)^{38} - 1 = 12.07927 \dots

= 1690 \cdot \frac{12.07927 \dots}{0.07}

分数を乗じる:

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

= \frac{12.07927 \dots \cdot 1690}{0.07}

数を乗じる:

12.07927 \dots \cdot 1690 = 20413.96868 \dots

= \frac{20413.96868 \dots}{0.07}

数を割る:

\frac{20413.96868 \dots}{0.07} = 291628.12408 \dots

= 291628.12408 \dots
