In this section, we will learn about pure surds as well as mixed surds. Definition of Pure Surd A surd is called a pure surd if it consists of a whole rational number under the root symbol. For example, $\sqrt{2}$ is a pure surd but $7\sqrt{2}$ is not. Examples of Pure Surd: (i) $\sqrt{11}, \sqrt{18}$ … Read more
The simple surds and the compound surds are two different types of surds. Here we will learn about them. Definition of Simple Surd A surd is called a simple surd if it contains only one term. More precisely, this type of surd is produced with only one root symbol. A simple surd is also known … Read more
