Question

Proof that √5-3 is a irrational number.​

Answer 1

Step-by-step explanation:

Since a & b are integers, we get 5b -a/b is rational, ... So we get 5b -a/b = √3 Since a & b are integers, we get 5b -a/b is rational, and so √3 is rational.

Answer 2

Step-by-step explanation:

since 5 a and b are integers 5b-a/b is rational so √3 is rational but this is a contradiction

hence 5-√3 is irrational
