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 help me with the following question thank you Suppose that A is a set and {Bi | i ∈ I} is an indexed families of sets. Prove that A × (Ui∈I Bi) = Ui∈I (A × Bi). This problem is similar to Theorem 4.1.3 and to Exercise 11 in Section 4.1 of your SNHU MAT299 textbook.
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. Verify the second assertion of Theorem 1.3.4, that for any collection of sets {Asher Ai iET iET Exercise 1.8. Prove...
