How to find order of the surds

Answer 1

The order of a surd indicates the index of root to be extracted.

In \(\sqrt[n]{a}\), n is called the order of the surd and a is called the radicand.

For example: The order of the surd \(\sqrt[5]{z}\) is 5.

(i) A surd with index of root 2 is called a second order surd or quadratic surd.

The surds which have the indices of root 2 are called as second order surds or quadratic surds. For example√2, √3, √5, √7, √x are the surds of order 2.

Example: √2, √5, √10, √a, √m, √x, √(x + 1) are second order surd or quadratic surd (since the indices of roots are 2).
