WebCombining Proofs, cont. I Now, employ proof by contradiction to show pr 2 is irrational. I Suppose pr 2 was rational. I Then, for some integers p;q: pr 2 = p q I This can be rewritten as p 2 = rq p I Since r is rational, it can be written as quotient of integers: p 2 = a b p q = ap bq I But this would mean p 2 is rational, a contradiction.
