Question

what is irrational number ?​

Answer 1

In mathematics,

Numbers are divided into 2 parts.

1. Rational numbers: Numbers which can be expressed in the form p/q where q is not equal to 0. For example: 2, ⅓, ⅖, 5, etc.
2. Irrational numbers: Numbers which cannot be expressed in the form p/q where q is not equal to 0. For example: √2, √3, π, etc

When an irrational number is present in denominator, we usually rationalize and bring it to the numerator.

Irrational numbers do not have a perfect value

A number is identified as Irrational number if it does not terminate nor have a repeating sequence.

☕ In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers.

☕ 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.

☕ 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.

✨ An Irrational Number is a real number that cannot be written as a simple fraction. Irrational means not Rational.
