Calcule o módulo de cada número complexo:?

Vamos lá z = a+bi (z) = a-bi (z) = conjugado z = 3-4i (z) = 3+4i z.(z) = (3-4i).(3+4i) Produto da soma e diferença. Fica, quadrado do primeiro menos o quadrado do segundo. 3² - 4²i² 3² = 3.3 = 9 4² = 4.4 = 16 i² = -1 Então: 9 - 16.(-1) 9 + 16 25 para o produto z.(z).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
