2699=699(1+r/(100))^{12}

解

2699 = 699 (1 + \frac{r}{100})^{12}

解

r = 100 12 \frac{2699}{699} - 100, r = - 100 12 \frac{2699}{699} - 100

+1

十進法表記

r = 11.91641 \dots, r = - 211.91641 \dots

解答ステップ

2699 = 699 (1 + \frac{r}{100})^{12}

辺を交換する

699 (1 + \frac{r}{100})^{12} = 2699

以下で両辺を割る

699

(1 + \frac{r}{100})^{12} = \frac{2699}{699}

(g (x))^{n} = f (a)

の場合, n は偶数, 解は

g (x) = n f (a), - n f (a)

解く

1 + \frac{r}{100} = 12 \frac{2699}{699} : r = 100 12 \frac{2699}{699} - 100

解く

1 + \frac{r}{100} = - 12 \frac{2699}{699} : r = - 100 12 \frac{2699}{699} - 100

解答は

r = 100 12 \frac{2699}{699} - 100, r = - 100 12 \frac{2699}{699} - 100
