WebJul 20, 2024 · Best answer Let x be some element in set A – B that is x ∈ (A – B) Now if we prove that x ∈ (A ∩ B’) then (A – B) = (A ∩ B’) x ∈ (A – B) means x ∈ A and x ∉ B Now x ∉ B means x ∈ B.’ Hence we can say that x ∈ A and x ∈ B'. Hence x ∈ A ∩ B.’ And as x ∈ A ∩ B’ and also x ∈ A – B we can conclude that A – B = A ∩ B.’ ← Prev Question Next Question → Webb) For (a; b) to be in R3 ∩ R5, we must have a < b or a = b. Since this never happens, i., the relation that never holds. c) Recall that 𝑅1 − 𝑅2 = 𝑅 1 ∩ 𝑅̅̅̅ 2. But R 2 = R 3 , so we are asked for R 1 ∩R 3. It is impossible for a > b and a < b to hold at the same time, so the answer is ;, i., the relation that never holds ... if j 5 and k 6 then the value of j++ k is
