Math Prob - Suppose x is a real number such that x + (1/x) is an integer. Show that x^n + (1/x^n) is an integer for all positive integers n.
Integer Proofs by Contradiction - Assume that n is a positive integer. Use the proof by contradiction method to prove:
(a) If 7n + 4 is an even integer, then n is an even integer.
(b) Prove: n is an even integer iff 7n + 4 i ...
Find the integer. - The square of an integer is 12 more than the integer. Find the integer.
For any integer a, argue that a + 3 > a + 2 - 1)For any integer a, argue that a + 3 > a + 2
3) An integer a is divisible by an integer b means there is an integer z such that a = b x z. use any properties of the integers through page 14 to pr ...
