can some please help me understand this question and also if it can be handwritten not typed thank you so much Let U be any set. Prove that for every B ∈ ℘(U) there is a unique D ∈ ℘(U) such that for every C ∈ ℘(U), C \ B = C ∩ D. This problem is similar to Examples 3.6.2 and 3.6.4 and to Exercise 8 in Section 3.6 of your SNHU MAT299 textbook.

Please help me prove 2,4, and 5. Thank you Theorem 17. Let A, B and C be sets. Then the following statements are true: (1) AB CA; (2) B CAUB; (3) A CAUB; (4) AB=BA; (5) AU (AUC) = (AUB) UC; (6) An(BNC) = (ANB) nC; (7) An (BUC) = (ANB) U (ANC); (8) AU (BAC) = (AUB) n(AUC).
12. Definition : Let Λ be a non-empty set. If for each a є Л there is a set Aa, the collection (Aa : α Ε Λ is called an indexed collection of sets. The set A is called the index set. Traditionally Λ is often the natural numbers-you are probably pretty used to seeing sets indexed by the natural numbers but it can in fact be any other set! Here's the exercise: Let Л-R+ (meaning the positive real numbers,...

Please give good proofs, thank you! Problem 15.4. Give three proofs that the union of two compact sets is a compact set. One proof for each a the three criteria in the theorem. So prove the union of two compact sets is a compact set, using: (a) the closed and bounded criterion; (b) sequential compactness; (c) topological compactness
Please prove a) and b), thank you. + B is a bijection, then (a) (Theorem 8.32) Let A and B be sets such that A is countable. If f: A B is countable. (b) (Theorem 8.33) Every subset of a countable set is countable.1
I really need someone to solve and explain the last two questions. Thank you! Exercise 1.5. Prove that if A and B are sets satisfying the property that then it must be the case that A - B. Exercise 1.6. Using definition (1.2.5) of the symmetric difference, prove that, for any sets A and B, AAB - (AUB)I(AnB). Exercise 1.7.
