Answer 1

Resposta:j10

Explicação passo-a-passo:(a) j2 + j3 − j6 − j8 (b) j2(− j3)(j4)(− j6) (c) (d) (a) As ... j3)][j4(−j6)] = 6(24) = 144 Alternativamente, j1 pode ser fatorado em cada ... reais: j2(−j3)(j4)(−j6) = (j1)4[2(−3)(4) (− 6)] = 1(144) = 144 (c) O denominador ... (b) (7,34 − j1,29) + (5,62 + j8,92) = (7,34 − 5,62) − j(1,29 + 8,92) = 1,72 − j10 ...
