Răspuns:
A = {0,1,2}
B = {-4,-3,-2,-1,0,1,2}
Explicație pas cu pas:
A U B = B = {-4,-3,-2,-1,0,1,2}
A n B = A = {0,1,2}
A - B = multimea vida
B - A = {-4,-3,-2,-1}
A ⊂ B - A
B ⊂ A - F
A ⊂ (A U B) - A
A ⊂ (B - A) - F
Explicație pas cu pas:
A={0;1;2}
B={-4;-3;-2;-1;0;1;2}
a)AUB={0;-1;1;-2;2;-3;-4}
A intersectat cu B={0;1;2}
A-B={multime vida}
B-A={-1;-2;-3;-4}
b)A inclus in B---Adevarat
B inclus in A---Fals
A inclus in AUB---Adevarat
A inclus in B-A---Fals.
Succes!
