Question

Show that 5 - V3 is irrational.​

Answer 1

Answer:yes

Step-by-step explanation:Let us assume the given number be rational and we will write the given number in p/q form

⇒5− V3=pq

⇒ 3=q/5q-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− V3

is irrational
