簡約 25000*((0.03)/(1-(1+0.03)))^{-12}

解

簡約

25000 \cdot (\frac{0.03}{1 - ( 1 + 0.03 )})^{- 12}

25000

解答ステップ

25000 (\frac{0.03}{1 - ( 1 + 0.03 )})^{- 12}

指数の規則を適用する:

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

(\frac{0.03}{1 - ( 1 + 0.03 )})^{- 12} = \frac{1}{( \frac{0.03}{1 - ( 1 + 0.03 )} ) ^{12}}

= 25000 \cdot \frac{1}{( \frac{0.03}{1 - ( 1 + 0.03 )} ) ^{12}}

(\frac{0.03}{1 - ( 1 + 0.03 )})^{12} = 1

= 25000 \cdot \frac{1}{1}

規則を適用

\frac{a}{1} = a

= 25000 \cdot 1

数を乗じる:

25000 \cdot 1 = 25000

= 25000
