Question

dados os conjuntos a= {3,5,7} e b= {3,9,15,35} A)= Determine AXB B)= Determine BXA

Answer 1

Olá,

O conjunto AXB (A cartesiano B), será:
AXB = {(3,3), (3,9), (3,15), (3,35), (5,3), (5,9), (5,15), (5,35), (7,3), (7,9), (7,15), (7,35)}

BXA = {(3,3), (3,5), (3,7), (9,3), (9,5), (9,7), (15,3), (15,5), (15,7), (35,3), (35,5), (35,7)}

Bons estudos ;)
