Question

Prove that 55 is irrational​

Answer 1

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 coprime numbers.

so, 5 = qp

p= ( 5)q

we know that 'p' is a rational number. so

( 5)q must be rational since it equals to pbut it doesnt occurs with

( 5)q since its not an integertherefore, p is not equal to ( 5)qthis contradicts the fact that ( 5) is an irrational numberhence our assumption is wrong and ( 5) is an irrational number
