0.195618=(1+x)^{12}-1

解答

0.195618 = (1 + x)^{12} - 1

解答

x = 12 1.195618 - 1, x = - 12 1.195618 - 1

+1

十进制

x = 0.01499 \dots, x = - 2.01499 \dots

求解步骤

0.195618 = (1 + x)^{12} - 1

交换两边

(1 + x)^{12} - 1 = 0.195618

将

1

到右边

(1 + x)^{12} = 1.195618

对于

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

，n 为偶数，解为

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

解

1 + x = 12 1.195618 : x = 12 1.195618 - 1

解

1 + x = - 12 1.195618 : x = - 12 1.195618 - 1

解为

x = 12 1.195618 - 1, x = - 12 1.195618 - 1
