Prove that `sqrt(3)` is irrational.

Text Solution

Verified by Experts

Let us assume that, `sqrt3` is rational. Then, `sqrt 3 = p div q` Where `p` and `q` are integers. then `p, q in Z` , `q ne 0` and co-primes then `GCD (p,q) =1`
`sqrt3 = p div q`
`=> p = (sqrt 3) q`
By squaring both sides, we get, ...
