For example =3.1444555525158 or 1.41421356237…… .
A number is called irrational, if it cannot be written in the form of p/q, where p and q are integers and q is not equal to 0
Irrational numbers: Irrational numbers are those which can’t be expressed in fractional form, i.e., in p/q form. They neither terminate nor do they repeat. They are also known as non- terminating non-repeating numbers.For example: Irrational numbers include ‘π’ which starts with 3.1415926535… and is never ending number, square roots of 2,3,7,11, etc. are all irrational numbers.

A number which cannot be written in the form of p/q is called irrational number.
A rational number which can\’t Xpress in p/ q form, it is denoted by Q\’, & it is not an imaginary number. ex : π, 5/0, √2 etc.
Number that are not in the in form of p/q.
A number which form p/ q are integers p=0 and q is 1 is called irrational number
A number ‘s’ is called irrational if it cannot be written in the form p/q, where p and q are integers and q ≠ 0. E.g.: E.g.: 1.234674322345634232789064590812343…… or ∏, √2 etc,\xa0

The numbers that can\’t be expressed in the form of p/q where q not equal to 0 is called irrational number.eg. √2

A no. is known as rational if it is not in the form of p/q and p and q are not integers . So we can say that the number is irrational.FOR EXAMPLE: 1.101001000100001……or in the form of pye or root 2, 3, 5, 7……….
A number ‘s’ is called irrational if it cannot be written in the form p/q, where p and q are integers and q ≠ 0. E.g.: E.g.: 1.234674322345634232789064590812343…… or ∏, √2 etc,

A numbe. whose decimal expression is non terminating and non repeating is called irrational no.For ex. pi
