Z=(20-12sqrt(3))/(2sqrt(3)-i)

解答

Z = \frac{20 - 12 3}{2 3 - i}

Z = \frac{- 72 + 40 3}{13} + i \frac{20 - 12 3}{13}

求解步骤

Z = \frac{20 - 12 3}{2 3 - i}

化简

\frac{20 - 12 3}{2 3 - i} : \frac{- 72 + 40 3}{13} + i \frac{20 - 12 3}{13}

Z = \frac{- 72 + 40 3}{13} + i \frac{20 - 12 3}{13}

- 4 + 7 d + 13 = 33

x + 14 = 35

g (r) = \frac{2}{r ^{2} - 1}

\frac{2 x}{3} + \frac{16}{3} = \frac{- 4 x}{2}

so l v e f or x, - 3 x + 2 y = - 4
