Sprawdź, czy A ⊂ B, B ⊂ A lub A = B:
a) A = {x : x ∈ N ∧ 6|x}, B = {x : x ∈ N ∧ 3|x}
b) A = {x : x ∈ R ∧ x ¬ −2}, B = {x : x ∈ R ∧ x < −1}
c) A = {2, 3, 5, 7, 11, 13}, B = {3, 5, 7, 11, 13, 17}
d) A = {x : x ∈ N ∧ 2|x}, B – zbiór liczb złożonych
e) A – zbiór liczb pierwszych, B – zbiór liczb nieparzystych
f) A = {x : x ∈ W ∧
√6 x ∈ W}, B = {x : x ∈ W ∧
√3 x ∈
W}
g) A = {x : x ∈ R ∧ 3x + 1 > 7}, B = {x : x ∈ R ∧ x >
2 ∧ x 6= 0}
