Question

Se A = (4,6} , B = {-3} e C = {0 , -8
Então, (AUB)x(C) é:


Se A = (4,6} , B = {-3} e C = {0 , -8}
Então, (AUB)x(BUC) é:

Answer 1

A = {4,6}
B = {-3}
C = {0,-8}

AUB = {-3,4,6} | União dos conjuntos A e B
(AUB)x(C) = {-3,0|-3,8|4,0|4,8|6,0|6,8}
-----------------------------------------------------------
A = {4,6}
B = {-3}
C = {0,-8}

AUB = {-3,4,6} | União dos A e B
BUC = {0,-3,-8} | União dos conjuntos B e C

(AUB)x(BUC) = {-3,0|-3,-3|-3,-8|4,0|4,-3|4,-8|6,0|6,-3|6,-8}
