Exercise 1.2(Real numbers) Question 1: Prove that √5 is irrational. Solutions: Let us assume, that √5 is rational number.where, x and y are co-primes and y ≠ 0. i.e. √5 = x/y. ⇒ y√5= x Squaring both the sides, we get, (y√5)2 = x2 ⇒5y2 = x2……………………………….. (1) Thus, x2 is divisible by 5, so x is also divisible by 5. Let … Read more
