z=(2+i)/(2-i)

Lösung

z = \frac{2 + i}{2 - i}

z = \frac{3}{5} + i \frac{4}{5}

Schritte zur Lösung

z = \frac{2 + i}{2 - i}

Vereinfache

\frac{2 + i}{2 - i} : \frac{3}{5} + i \frac{4}{5}

z = \frac{3}{5} + i \frac{4}{5}

so l v e f or f, f (f (n)) + f (n + 1) = n + 2

f = 2 lo g_{10} (10)

0.8 + r = 12.6

4 x - 7 = 2 x + 9

9 (11 - x) = 3 (3 x - 9)
