Question
What are irrational numbers? How do they differ from rational numbers? Give examples.

Answer

A number that can neither be expressed as a terminating decimal nor be expressed as a repeating decimal is called an irrational number. A rational number, on the other hand, is always a terminating decimal, and if not, it is a repeating decimal.
