化简 (-5-2i)/(-3+5i)

解答

化简

\frac{- 5 - 2 i}{- 3 + 5 i}

\frac{5}{34} + \frac{31}{34} i

求解步骤

\frac{- 5 - 2 i}{- 3 + 5 i}

乘以共轭根式

\frac{- 3 - 5 i}{- 3 - 5 i}

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

化简

\frac{( - 5 - 2 i ) ( - 3 - 5 i )}{( - 3 + 5 i ) ( - 3 - 5 i )} : \frac{5 + 31 i}{34}

= \frac{5 + 31 i}{34}

Rewrite in standard complex form:

\frac{5}{34} + \frac{31}{34} i

= \frac{5}{34} + \frac{31}{34} i
