 # Quick Answer: Is Root 2 Root 3 A Rational Number?

## How do you prove √ 2 is irrational?

Proof that root 2 is an irrational number.Answer: Given √2.To prove: √2 is an irrational number.

Proof: Let us assume that √2 is a rational number.

So it can be expressed in the form p/q where p, q are co-prime integers and q≠0.

√2 = p/q.

Solving.

√2 = p/q.

On squaring both the side we get, =>2 = (p/q)2 => 2q2 = p2……………………………..(1).
