20 Examples of Irrational Numbers

When talking about “numbers”We refer to those mathematical concepts that represent a certain quantity in relation to a unit. Within these mathematical expressions, rational and irrational numbers are identified:

Examples of irrational numbers

1. π (pi). This is perhaps the best known irrational number of all. It is the expression of the relationship that exists between the diameter of a sphere and its length. Pi then is 3.141592653589 (…), although in general it is known simply as 3.14.
2. √5. 2.2360679775
3. √123. 11.0905365064
4. and. It is the Euler number and it is the curve that is observed in electrical tissues and that appears in processes such as radioactive radiation or in growth processes. Euler's number is: 2.718281828459 (…).
5. √3. 1.73205080757
6. √698. 26.4196896272
7. Golden. This number, which is represented by the following symbol Φ, which is nothing more than the Greek letter Fi. This number is also known as golden ratio, golden number, mean, golden ratio, among others. What this irrational number expresses is the proportion that exists between two parts of a line, either of something found in reality or of a geometric figure. But in addition, the golden number is widely used by visual artists when establishing proportions in their works. This number is: 1.61803398874989.
