... This is a proof by contraposition. Assume that x1 is rational. By definition of a rational number, x1 = pq for some integers p and q, with q 6= 0. We also know that x1 cannot equal 0, since there is no way to divide 1 by anything and get 0. Thus, p 6= 0. It follows that x = pq , which means that x c ...
