Let us assume that √5 is a rational number. we know that the rational numbers are in the form of p/q form where p,q are intezers. so, √5 = p/q p = √5q we know that 'p' is a rational number. so √5 q must be rational since it equals to p but it doesnt occurs with √5 since its not an intezer therefore, p =/= √5q this contradicts the fact that √5 is an irrational number hence our assumption is wrong and √5 is an irrational number.

3Thank You
