化简 (7-6i)/(1-7i)

解答

化简

\frac{7 - 6 i}{1 - 7 i}

\frac{49}{50} + \frac{43}{50} i

求解步骤

\frac{7 - 6 i}{1 - 7 i}

乘以共轭根式

\frac{1 + 7 i}{1 + 7 i}

= \frac{( 7 - 6 i ) ( 1 + 7 i )}{( 1 - 7 i ) ( 1 + 7 i )}

化简

\frac{( 7 - 6 i ) ( 1 + 7 i )}{( 1 - 7 i ) ( 1 + 7 i )} : \frac{49 + 43 i}{50}

= \frac{49 + 43 i}{50}

Rewrite in standard complex form:

\frac{49}{50} + \frac{43}{50} i

= \frac{49}{50} + \frac{43}{50} i

6 m - 7 = 4 m + 13

f a c t or 4 x^{3} - 12 x^{2} - 9 x - 1

12 > 14 + x

x^{2} + 4 x - 10 = 0

45 = - 5 k
