WebTo show set equality you show ⊃, ⊂ respectively. ⊂: Let x ∈ A. Then x either in A ∩ B or in A ∩ Bc = A − B, so x ∈ (A ∩ B) ∪ (A − B). ⊃: Let x ∈ (A ∩ B) ∪ (A − B). Then either x in A ∩ B or x in A ∩ Bc. But in both cases x ∈ A, therefore x ∈ A. answered Jan 18, 2011 at 18:04 Rudy the Reindeer 44.9k 25 148 320 Add a comment 2 Web90 Hasan Sankari, Mohammad Abobala, On The Classification of the group of units of Rational and Real 2-cyclic refined neutrosophic rings Open problem 1: If the ring R with no zero divisors, then is the group of units of 2(𝐼) is isomorphic to 𝑈( )×𝑈( )×𝑈( ). bair hugger medical https://theros.net
