Web1. The number 3 √ 2 is not a rational number. Solution We use proof by contradiction. Suppose 3 √ 2 is rational. Then we can write 3 √ 2 = a b where a, b ∈ Z, b > 0 with gcd(a, b) = 1. We have 3 √ 2 = a b 2 = a 3 b 3 2 b 3 = a 3. So a 3 is even. It implies that a is even (because a odd means a ≡ 1 mod 3 hence a 3 ≡ 1 mod 3 so a 3 ... WebJun 25, 2024 · An irrational number is a number that can’t be expressed as a ratio between two numbers. It is number where the digits to the right of the decimal go on indefinitely without a repeating pattern. That means whole numbers are never irrational numbers because the only number after the decimal would be 0.

WebDo irrational numbers exist in nature? My answer is no. The reason is that we can never perform any measurement whose result is an irrational number. In this sense, perfect geometrical entities, such as spheres, squares, circles, etc... do not exist in nature.
