Question

2. Fie mulțimile A={-2; -1; 3} și B={0; 2}. Determinați A X B, B X A, A X A, B X B.​

Answer 1

Răspuns:

AXB = ((-2,0), (-2,2), (-1,0), (-1,2), (3,0), (3,2))

BXA = ((0,-2), (0,-1), (0,3), (2,-2), (2,-1), (2,3))

AXA = ((-2,-2), (-2,-1), (-2,3), (-1,-2), (-1,-1), (-1,3), (3,-2), (3,-1), 3,3))

BXB = ((0,0), (0,2), (2,0), (2,2))
