Witryna28 mar 2024 · Proving That Root 2 Is Irrational. Let's assume that √2 is rational and therefore can be written as a fraction in lowest terms p/q, where p and q are integers and q ≠ 0. √2 = p/q. Square both sides. 2 = p 2 /q 2. Multiply both sides by q 2. 2q 2 = p 2. As p 2 is equal to two times a whole number, it must be even.
