Demonstrate There Is An Irrational Number Between Any Two

WebAs r is rational, r - 5 is rational \Rightarrow \sqrt {2} ⇒ 2 is rational But this contradicts the fact that \sqrt {2} 2 is irrational. Hence, our assumption is wrong. ∴ 5 + \sqrt {2} 5+ 2 is an irrational number. \text { (ii) } 3 - 5\sqrt {3} (ii) 3−5 3 Let us assume that 3 - 5\sqrt {3} 3−5 3 is a rational number, say r. Then, WebIn this proof we want to show that √2 is irrational so we assume the opposite, that it is rational, which means we can write √2 = a/b.
