Question

Prove that √5 is an irrational number​

Answer 1

Answer:

It is and irrational number

Step-by-step explanation:

$\sqrt{5} = 2.236067978$

This shows no signs of ending. No number sequences repeat themselves, thus showing signs of never ending. This cannot be written as an integer therefore, it is irrational.

I found this online:

"This is a contradiction since a number cannot have an odd number of prime factors and an even number of prime factors at the same time. The assumption that square root of 5 is rational is wrong. Therefore, square of 5 is irrational".
