Topic: Radical Expressions
Subtopic: Operations II - Add & Subtract

Overview

Expand your knowledge of radical expressions by adding and subtracting radical expressions.

Rule: You can only add or subtract "like" radical expressions, meaning that they must have the same index and identical radicands (stuff under the radical sign).

For example a square root and a cube root cannot be added, they are not like radicals since they don't have the same index.

Objectives

By the end of this topic you should know and be prepared to be tested on:

Terminology
