Irrational numbers don't exist
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 ... WebRational numbers are all numbers that can be written as the ratio (or fraction) of 2 integers. This is the basic definition of a rational number. Here are examples of rational numbers: -- All integers. Numbers like 0, 1, 2, 3, 4, .. etc. And like -1, -2, -3, -4, ... etc. -- All terminating decimals. For example: 0.25; 5.142; etc.

Case 1: It is rational: 3.1 Let p = q = 2 and … WebNon-rational numbers like \sqrt2 are called irrational numbers. Tradition says that Pythagoras first proved that \sqrt2 is irrational, and that he sacrificed 100 oxen to celebrate his success. Pythagoras' proof is the one still usually taught today.
WebA number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express … WebWe once believed all numbers could be expressed as a ratio of two integers, hence the term rational number. The diagonal of a unit square is 2 which is irrational. This is easy to see. Take two unit squares and cut them along their diagonals. You now have four right …
WebI wounder, if you also believe that irrational numbers exist. To be more specific, I'm not talking about all irrational numbers, but only those that can not be represented in any useful way, e.g. as a result to a specific equation not involving non-useful irrational numbers (which should be infinitely more than those that can). WebNo. An irrational number is strictly a number that cannot be written as a ratio of two integers. For example, 0.33333... = 1/3, which means it is a rational number. For irrational …
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. Therefore, so curvilinear trajectories, or even smooth manifolds, don't exist either.
