Question

URGENTE Calcule o modulo do complexo W sendo Z1= (1/3 + i) e Z2= (1/2 + i) onde w é igual a : W = (Z1+ Z2) + (Z2 - Z1)

Answer 1

Olá, Dartyers.

$z_1= \frac13 + i, z_2= \frac12 + i \\\\ w = (z_1+ z_2) + (z_2 - z_1)=z_1+ z_2 + z_2 - z_1=2z_2=2( \frac12 + i)=1+2i \\\\ |w|=\sqrt{1^2+2^2}=\sqrt{1+4}=\sqrt5$
