Answer (1)
30th Jul, 2025
Dear student,
To demonstrate that the square root of 5 is irrational, you have to use proof by contradiction. First you have to assume √5 is rational, express it as a fraction a/b where a and b are coprime, and then show that this leads to a contradiction, proving the initial assumption false.
Thank you
