WebExample 1 : Prove that √2 is an irrational number. Solution : Let √2 be a rational number. Then it may be in the form a/b √2 = a/b Taking squares on both sides, we get 2 = a2/b2 2b2 = a2 a2 divides 2 (That is 2/a2) Then a also divides 2. Let a = 2c 2b2 = a2 By applying the value here, we get 2b2 = (2c)2 2b2 = 4c2 b2 = 2c2 Web7 Dec 2024 · Example 2: Find two irrational numbers between 2 and 2.5. Sol. If a and b are two distinct positive rational numbers such that ab is not a perfect square of a rational number, then is an irrational number lying …
