1.05=(1+x/(12))^{12}

解答

1.05 = (1 + \frac{x}{12})^{12}

解答

x = 0.04888 \dots, x = - 24.04888 \dots

求解步骤

1.05 = (1 + \frac{x}{12})^{12}

交换两边

(1 + \frac{x}{12})^{12} = 1.05

对于

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

，n 为偶数，解为

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

解

1 + \frac{x}{12} = 12 1.05 : x = 0.04888 \dots

解

1 + \frac{x}{12} = - 12 1.05 : x = - 24.04888 \dots

解为

x = 0.04888 \dots, x = - 24.04888 \dots
