Question

what is irrational number ?​

Answer 1

Answer: Irrational numbers are real numbers that, when expressed as a decimal, go on forever after the decimal and never repeat. ... This is opposed to rational numbers, like 2, 7, one-fifth and -13/9, which can be, and are, expressed as the ratio of two whole numbers. In the case of irrational numbers, the decimal expansion does not terminate, nor end with a repeating sequence. For example, the decimal representation of π starts with 3.14159, but no finite number of digits can represent π exactly, nor does it repeat.  There are many irrational numbers that cannot be written in simplified form. Some of the examples are: √8, √11, √50, Euler's Number e = 2.718281, Golden ratio, φ= 1.618034.
