WebbAs 7 divides 7m 2, so 7 divides q 2 but 7 is prime. \Rightarrow 7 \text { divides } q \qquad \text { (Theorem 1)} ⇒ 7 divides q (Theorem 1) Thus, p and q have a common factor 7. This contradicts that p and q have no common factors (except 1). Hence, \sqrt {7} 7 is not a rational number. So, we conclude that \sqrt {7} 7 is an irrational number. WebbThis contradicts that p and q have no common factors (except 1). Hence, \sqrt {2} 2 is not a rational number. So, we conclude that \sqrt {2} 2 is an irrational number.
