## What is the square root of 2 as a fraction?

A famous example is the square root of 2, which is roughly 1.4142, and denoted √2. If √2 were rational, it must be expressible in the form a/b, where a and b are natural numbers (that is, whole numbers). We can write this in equation form, √2 = a/b, then give it a quick mathematical kick of the tyres.

## How do you prove that the square root of 2 is irrational?

Specifically, the Greeks discovered that the diagonal of a square whose sides are 1 unit long has a diagonal whose length cannot be rational. By the Pythagorean Theorem, the length of the diagonal equals the square root of 2. So the square root of 2 is irrational!
