Răspuns:
Explicație pas cu pas:
A = {-2, -1, 0, 1, 2}
numere prime de forma 2x: 23; 29
B = {3, 9}
A U B = {-2, -1, 0, 1, 2, 3, 9}
A ∩ B = ∅
A \ B = {-2, -1, 0, 1, 2}
B \ A = {3, 9}
A={x∈Z | -2≤x≤2}
A={-2,-1,0,1,2}
B={x∈N | 2x este numar prim}
B={3,9}
A∪B={-2,-1,0,1,2,3,9}
A∩B=Ф
A-B={-2,-1,0,1,2}
B-A={3,9}
