Question

Dado os números complexos z= 3-i, w=4 +2i e v= -2 +3i
resolva as operações a baixo:
(A) z + v
(B) v - w
(C) w- z
(D) v - z

Answer 1

Resposta:

A) z + v

3-i + (-2+3i) = 3-i -2+3i

1+2i

B) v - w

-2 +3i - (4+2i) = -2 +3i -4 -2i

-2+i

C) w - z

4+2i - (3-i) = 4+2i -3+i

1+3i

D) v - z

-2 +3i -(3-i) = -2 +3i -3+i

-5+4i
