z=(-2)/(1+sqrt(3i))

解答

z = \frac{- 2}{1 + 3 i}

z = - \frac{( - 3 i + 1 ) ( 1 + 3 i )}{5}

求解步骤

z = \frac{- 2}{1 + 3 i}

化简

\frac{- 2}{1 + 3 i} : - \frac{( - 3 i + 1 ) ( 1 + 3 i )}{5}

z = - \frac{( - 3 i + 1 ) ( 1 + 3 i )}{5}

\frac{6}{5} x + \frac{5}{4} = - 4

3 x - 10 + 13 = - 2 x + 28

x - 12 = 4 - 2 x

6 - m = 5 m + 30

so l v e f or a, 6 x + a = 5 (x + t)
