Answer» 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 integers.so,√5 = p/q p =√5qwe know that 'p' is a rational number. so√5 q must be rational since it equals to pbut it doesnt occurs with√5 since its not an integertherefore, p =/=√5qthis contradicts the fact that√5 is an irrational numberhence our assumption is wrong and√5 is an irrational number. |
