z=((4+5i))/((7+2i))

Lösung

z = \frac{( 4 + 5 i )}{( 7 + 2 i )}

z = \frac{38}{53} + i \frac{27}{53}

Schritte zur Lösung

z = \frac{( 4 + 5 i )}{( 7 + 2 i )}

Vereinfache

\frac{4 + 5 i}{7 + 2 i} : \frac{38}{53} + i \frac{27}{53}

z = \frac{38}{53} + i \frac{27}{53}

(\frac{1}{25})^{3} x = 5^{2} x - 16

(x - 2)^{2} = (x - 4) (x + 4)

so l v e f or x, (y + 4) = - 3 (x - 3)

\frac{1}{2} a + b + 2 x = \frac{1}{2} a + \frac{1}{b} + \frac{1}{2} x

2 \frac{x}{3} - \frac{8}{3} = \frac{17}{6}
