Are -3036661 451 and 5 irrational numbers? - Answers

NO !!! However, the square root of '5' is irrational 5^(1/2) = 2.236067978... Casually an IRRATIONAL NUMBER is one where the decimals go to infinity and there is no regular order in the decimal numbers. pi = 3.141592.... It the most well known irrational number. However, 3.3333.... Is NOT irrational because there is a regular order in the decimals. Here is a definitive statement of Irrational Numbers. Irrational numbers are real numbers that cannot be represented as simple fractions. An irrational number cannot be expressed as a ratio, such as p/q, where p and q are integers, q≠0. It is a contradiction of rational numbers. Irrational numbers are usually expressed as R\Q, where the backward slash symbol denotes ‘set minus’. It can also be expressed as R – Q, which states the difference between a set of real numbers and a set of rational numbers.
