100 PONTOS

Answer 1

Resposta:

z1=2-i

z2=1/3+i

a) z1+z2=

$2 - i + \frac{1}{3} + i = \\ 2 \frac{}{} + \frac{1}{3} - i + i = \\ 2 + \frac{1}{3} + 0 = \\ 2/1 + \frac{1}{3} = \\ \frac{6 + 1}{3} = \\ \frac{7}{3}$

Answer 2

Explicação passo-a-passo:

$\sf z_1+z_2=2-i+\dfrac{1}{3}+i$

$\sf z_1+z_2=2+\dfrac{1}{3}-i+i$

$\sf z_1+z_2=2+\dfrac{1}{3}\not{-i}+\not{i}$

$\sf z_1+z_2=2+\dfrac{1}{3}$

$\sf z_1+z_2=\dfrac{6}{3}+\dfrac{1}{3}$

$\sf z_1+z_2=\dfrac{6+1}{3}$

$\sf \red{z_1+z_2=\dfrac{7}{3}}$
