Qual ó módulo dos números complexos
a) Z= 6 + 2i
b) Z= 1-2i
c) Z=8i

Answer 1

Resposta:

a) Z = 6 + 2i

b) Z = 1 - 2i

c) Z = 8i

$a)|Z|=\sqrt{6^2+2^2}\\\\|Z|=\sqrt{36+4} \\\\|Z|=\sqrt{4.10}\\\\|Z|=2\sqrt{10}\\\\b)|Z|=\sqrt{1^2+(-2)^2}\\\\|Z|=\sqrt{1+4}\\\\|Z|= \sqrt{5} \\\\|Z|=\sqrt{8^2}\\\\|Z|=8}$
