Answer 2

Answer:

Let us assume the given number be rational and we will write the given number in p/q form

⇒5−3=qp

⇒3=q5q−p

We observe that LHS is irrational and RHS is rational, which is not possible. 

This is contradiction. 

Hence our assumption that given number is rational is false 

⇒5−3  is irrational
