WebbAs 5 divides 5m 2, so 5 divides q 2 but 5 is prime. \Rightarrow 5 \text { divides } q \qquad \text { (Theorem 1)} ⇒ 5 divides q (Theorem 1) Thus, p and q have a common factor 5. This contradicts that p and q have no common factors (except 1). Hence, \sqrt {5} 5 is not a rational number. So, we conclude that \sqrt {5} 5 is an irrational number.
