Let S be a nonempty subset of an order field F. Write definitions for lower bound of S and greatest lower bound of S. Prove that if F is a complete ordered field and the nonempty subset S has a lower bound in F, then S has a greatest lower bound in F.
Let p be prime and G the multiplicative group of units Up=[a]Zp[a][0]. Use Lagranges Theorem in G to prove Fermats Little Theorem in the form [a]p=[a] for any aZ. (compare with Exercise 54 in section 2.5) Let p be a prime integer. Prove Fermats Little Theorem: For any positive integer a,apa(modp). (Hint: Use induction on a, with p held fixed.)
Using Richard Hammack's book of Elements of Discrete Mathematics chapter 18 in cardinality. N = natural numbers Using Cantor’s diagonalization, prove that |(0, 1)| ≠ |N|.

Prove that the cardinality of the open unit interval, (0,1), is equal to the cardinality of the open unit cube: {(x,y,z) E R^3 such that 0 <x<1, 0<y<1, 0<z<1}. Hint: model your arugment on Cantor's proof for the interval and the open square. Consider the decimal expansion of the faction 12/999.

Say that X ⊆ Ris closed under multiplication if for all x, y ∈ X, we have thatxy ∈X.a. Give three examples of finite subsets of Rwhich are closed under multiplication.b. Give an example of an infinite proper subset of Rwhich is closed under multiplication. Prove your answer.c. Give an example of an infinite proper subset of Rwhich is not closed under multiplication. Prove your answer.
How do I prove this: Let a, b ∈ Z. Give an example of an integer x so that x∣a and x∣b and If x∣a and x∣b, can you give an upper bound on x? i.e. does there exist some m ∈ Z so thatx ≤ m?
It's not asking to prove it's a subset. It's asking to prove it's a bejection.
Let S be the set of all sequences of O's and 1's. Without using the theorem that the countable union of countable sets is countable, show that T = UTz is k=1 denumerable. You may just describe an enumeration of the elements of T. You don't have to define a bijection anymore and verify that it is a bijection. Hint: Think of how Q+ is denumerable.
