化简 ((1+3i))/(-3i)

解答

化简

\frac{( 1 + 3 i )}{- 3 i}

- 1 + \frac{1}{3} i

求解步骤

\frac{1 + 3 i}{- 3 i}

乘以共轭根式

\frac{- i}{- i}

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

化简

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

= \frac{- i + 3}{- 3}

Rewrite in standard complex form:

- 1 + \frac{1}{3} i

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

x^{2} + 5 x - 9 = 0

s im pl i f y \frac{4}{5} \cdot 2

10 x^{2} - 6 = 4 x

x^{2} + 20 x + 91 = 0
