Proof irrational
WebMar 28, 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. WebApr 17, 2024 · For example, we will prove that √2 is irrational in Theorem 3.20. We then see that √2√2 = 2 and √2 √2 = 1. which shows that the product of irrational numbers can be rational and the quotient of irrational numbers can be rational. It is also important to realize that every integer is a rational number since any integer can be written as a fraction.

He used a proof by contradiction. First Euclid assumed √2 was a rational number. He then went on to show that in the form p/q it can always be simplified.
