Webb28 mars 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. Webb3 Answers.

Therefore, 2+ … mark helprin authorWebbBy assuming that √2 is rational, we were led, by ever so correct logic, to this contradiction. So, it was the assumption that √2 was a rational number that got us into trouble, so that assumption must be incorrect, which means that √2 must be irrational.

An Irrational Number is a real number that cannot be written as a simple fraction: 1.5 is rational, ... But √4 = 2 is rational, and √9 = 3 is rational ..... so not all roots are irrational. Note on Multiplying Irrational Numbers. Have a look at this: mark helmuth wrcWebbThis shows that our original assumption that √ 2 is a rational number cannot be true. Therefore, √ 2 is not rational. This exact same reasoning can be used to show that the square root of any number that is not a perfect square is not rational.
