解

簡約

80000 \cdot \frac{1}{( 1 + 0.06 ) ^{30}}

13928.81047 \dots

解答ステップ

80000 \cdot \frac{1}{( 1 + 0.06 ) ^{30}}

数を足す:

1 + 0.06 = 1.06

= 80000 \cdot \frac{1}{1.0 6 ^{30}}

分数を乗じる:

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

= \frac{1 \cdot 80000}{1.0 6 ^{30}}

数を乗じる:

1 \cdot 80000 = 80000

= \frac{80000}{1.0 6 ^{30}}

1.0 6^{30} = 5.74349 \dots

= \frac{80000}{5.74349 \dots}

数を割る:

\frac{80000}{5.74349 \dots} = 13928.81047 \dots

= 13928.81047 \dots
