A number which cannot be written in the form a/b , where a and b are integers and b ≠ 0 is called a irrational number. Irrational numbers which have non-terminating and non-repeating decimal representation.The sum or difference of a two irrational numbers is also rational or an irrational number.

Those numbers which can not written in the form of P and where p and q are not equal to zero they are examples are under root 2 under root 3 under root 5 under root 7 we also say that the square root of all prime number is called irrational number
those\xa0nos whose decimal expansion is\xa0non-terminating\xa0non-repeating are called Irrational\xa0nos. such as 1.01001000100001…..\xa0
