Question

What is a pure surd?

Answer 1

A surd in which the whole of the rational number is under the radical sign and makes the radicand, is called pure surd. In other words a surd having no rational factor except unity is called a pure surd or complete surd.

Answer 2

A surd is a number or quantity that cannot be expressed as the ratio of two integer s. The term also refers to a symbol (√ ) that is sometimes used to indicate that the number or quantity that follows it is a root.
