化简 ((3+5i))/((1-2i))

解答

化简

\frac{( 3 + 5 i )}{( 1 - 2 i )}

- \frac{7}{5} + \frac{11}{5} i

求解步骤

\frac{3 + 5 i}{1 - 2 i}

乘以共轭根式

\frac{1 + 2 i}{1 + 2 i}

= \frac{( 3 + 5 i ) ( 1 + 2 i )}{( 1 - 2 i ) ( 1 + 2 i )}

化简

\frac{( 3 + 5 i ) ( 1 + 2 i )}{( 1 - 2 i ) ( 1 + 2 i )} : \frac{- 7 + 11 i}{5}

= \frac{- 7 + 11 i}{5}

Rewrite in standard complex form:

- \frac{7}{5} + \frac{11}{5} i

= - \frac{7}{5} + \frac{11}{5} i

\frac{x - 3}{4} < \frac{7}{3}

s im pl i f y lo g_{3} (25)

(x + 6)^{2} - 16 = 0

s im pl i f y \frac{f ( 7 - 7 x + h ) - f ( 7 - 7 x )}{h}
