3. Identify the hypothesis and conclusion in the following statements. Then, find a counter example showing that the statement is false. Here n, m, and p are originally assumed to be integers. Statement 1. If m and n are integers, then m/n is an integer. Statement 2. If m and n are positive integers, then m - n is a positive integer. Statement 3. If p is an odd prime number, then p^2 + 2 is a prime number. Statement...

write the following sentences as quantified logical statements, using the universal and existential quantifiers, and defining predicates as needed. Second, write the negations of each of these statements in the same way. Finally, choose one of these statements to prove. If it is true, prove it, and if it is false, prove its negation. Your proof need not use symbols, but can be a simple explanation in plain English. 1. If m and n are positive integers and mn is...
