(x-4)2=5

解答

(x - 4) 2 = 5

x = \frac{13}{2}

十进制

x = 6.5

求解步骤

(x - 4) \cdot 2 = 5

两边除以

2

x - 4 = \frac{5}{2}

将

4

到右边

x = \frac{13}{2}

so l v e f or x, \frac{( x + y )}{6} + \frac{13}{y} = \frac{( 4 - y )}{6}

so l v e f or x, 4 x - y + \frac{z}{2} = 0

so l v e f or x, pq = (6 x + 5) + (9 x)

so l v e f or x, 2 \frac{x}{6} + 3 \frac{y}{6} = 13

v n + 1 = v n \cdot (n + 1) (n + 3) (n + 2)^{2}
