化简 2/(6+5i)

解答

化简

\frac{2}{6 + 5 i}

\frac{12}{61} - \frac{10}{61} i

求解步骤

\frac{2}{6 + 5 i}

乘以共轭根式

\frac{6 - 5 i}{6 - 5 i}

= \frac{2 ( 6 - 5 i )}{( 6 + 5 i ) ( 6 - 5 i )}

化简

\frac{2 ( 6 - 5 i )}{( 6 + 5 i ) ( 6 - 5 i )} : \frac{12 - 10 i}{61}

= \frac{12 - 10 i}{61}

Rewrite in standard complex form:

\frac{12}{61} - \frac{10}{61} i

= \frac{12}{61} - \frac{10}{61} i

x^{2} - 4 = - 3
