Web3 jul. 2024 · I am stuck on how to elegantly show that if x is an element of (A ∩ B), it is also an element of A. This is what I have come up with until now: x ∈ ( A ∩ B) ≡ x ∈ A ∧ x ∈ B. … Webif A ⊆ B, then A ∪ B = B For example, if A = {2n n ∈ ℕ} and B is the set of integers, then A ∪ B = B, since set A is the set of positive even integers, which is a subset of all integers. Commutative law The commutative law states that the order in which the union of two sets is taken does not matter. Given two sets, A and B: A ∪ B = B ∪ A
