- Simple Surd - Pure Surd - Similar surds - Mixed surds - compound surds - Binomial surd

Simple Surd:

A simple surd is one in which the root symbol contains only a number.


Pure Surd:

Irrational surds are referred to as pure surds.


Similar Surd:

Surds that have the same common factors are referred to as similar surds.


Mixed Surds:

A mixed surd is a number that can be written as a product of rational and irrational numbers.


Compound Surds:
