((1+r)/(100))^{10}=1.5775

解

(\frac{1 + r}{100})^{10} = 1.5775

解

r = 100 10 1.5775 - 1, r = - 100 10 1.5775 - 1

+1

十進法表記

r = 103.66390 \dots, r = - 105.66390 \dots

解答ステップ

(\frac{1 + r}{100})^{10} = 1.5775

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

の場合, n は偶数, 解は

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

解く

\frac{1 + r}{100} = 10 1.5775 : r = 100 10 1.5775 - 1

解く

\frac{1 + r}{100} = - 10 1.5775 : r = - 100 10 1.5775 - 1

解答は

r = 100 10 1.5775 - 1, r = - 100 10 1.5775 - 1
