Hey friend Ur answer is
Definition of Pure surds
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.
For example, each of the surds √7, √10,
Definition of mixed surds
A surd having a rational co-efficient other than unity is called a mixed surd.
In other words if some part of the quantity under the radical sign is taken out of it, then it makes the mixed surd.
For example, each of the surds 2√7
In the following example we are going to learn how to simplify radical expressions.
\sqrt{x}x TO x^{1/2}x1/2
