WebbSince, p, q are integers, 2pqp 2+q 2 is a rational number. => 3 is a rational number. This contradicts the fact that 3 is irrational. Thus, our assumption is incorrect. Therefore, 2+ … WebbProve that √ 7 is an irrational number. Solution Let us assume that √ 7 is a rational number. So it t can be expressed in the form p q where p, q are co-prime integers and q ≠ 0 √ 7 = p q Here p and q are coprime numbers and q ≠ 0 √ 7 = p q On squaring both the side we get, √ 7 2 = p q 2 ⇒ 7 = p q 2 ⇒ 7 = p 2 q 2 ⇒ 7 q 2 = p 2 ……………………………..

Webb10 apr. 2024 · This means that 2 divides b2, and so 2 divides b Therefore, a and b have at least 2 as a common factor. But this contradicts the fact that a and b have no common factors other than 1. This contradiction has arisen because of our incorrect assumption that √2 is rational. So, we conclude that √2 is irrational. ← Prev Question Next Question → WebbYes, 2√3 is irrational. 2 × √3 = 2 × 1.7320508075688772 = 3.464101615137754..... and the product is a non-terminating decimal. This shows 2√3 is irrational. The other way to prove this is by using a postulate which says that if we multiply any rational number with an irrational number, the product is always an irrational number. mama\u0027s family cast members
