let √2 be a rational number √2= p/q, where p,q are integers, q is not equal to 0 , p,q have no common factor (except 1) 2=p^2/q^2 p^2=2q^2........(i) As 2 divides 2q^2 so, 2 divides p^2, but 2 is a prime number so, 2 divides p lets assume p^2 = 2m (m is an integer) substitute the value of p^2 in (i) p^2= 2q^2 (2m)^2 = 2q^2 4m^2= 2q^2 2m^2= q^2 (as 2 and 4 get divide by 2) As 2 divides 2m^2 so, 2 divides q^2, but 2 is a prime number so, 2 divides q here, p, q have a common factor 2. This contradicts the fact that p, q have no common factor(except 1) therefore, √2 is an irrational number Hope it helps Now you must be in class 10 but I saw the comment right now....I am in class 9....and I have my maths half yearly examination on 30th September Thankyou
