I’m having a bit of trouble with Problem 8b. Please give a thorough explanation. Thank you.
hmwk-1.pdf Explain. Problem 6: Show that if A x B = B x A then A = B. Problem 7: Prove the following properties of operations on sets (bel (a) A\BCA (b) If ACB, then AUB= B and AnB = A (c) (A\B) \ C = (A \ C) \(B\C) (d) (A\C) n (C\ B) = 0 Problem 8: Can you conclude that A = Bif (a) AUC = BUC? (b) AUC= BUC and AnC=BnC? Explain. Problem 9: Find U₁1 A₁ and 1 A; if for every positive integer (a) A₁ = {i,i+1,i+2,...} (b) Ai = {0,i,i+1} (c) A = {x: x is a real number such that 0 < x <i}. Problem 10. Determine whether these statements are true or false. (a) 0 = {0} (b) 0 ≤ {0} (c) {{0}} ℃ {{0}, {0}}. Your submnissions must be typed (wordprocessed), and submit
