解答

(1 + \frac{x}{4})^{4} = 22.5

解答

x = 4.71175 \dots, x = - 12.71175 \dots

求解步骤

(1 + \frac{x}{4})^{4} = 22.5

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}{4} = 4 22.5 : x = 4.71175 \dots

解

1 + \frac{x}{4} = - 4 22.5 : x = - 12.71175 \dots

解为

x = 4.71175 \dots, x = - 12.71175 \dots
