Guiding question: What is a simplified radical?

Chapter 10: Radical expressions and equations

Radical Expressions Any expression that contains a radical (square root symbol) is known as a radical expression.

Radical Expressions Any expression that contains a radical (square root symbol) is known as a radical expression. Example: √5,

Simplifying Radicals Simplest radical form means that: the quantity under the radical has no perfect square as its factor, and there are no radicals in the denominator.

Simplifying Radicals What are the perfect squares? 1, 4, 9, 16, etc. So when we simplify, we make sure that the number under the radical is not divisible by any of these numbers.

Simplifying Radicals Example: Simplify √28

Simplifying Radicals Example: Simplify √28 =

Simplifying Radicals Example: Simplify √28 = To help simplify radicals we can use the: Multiplication property of square roots a ≥ 0, b ≥ 0

Simplifying Radicals Therefore √28 =

Simplifying Radicals Therefore √28 = = 2√7

Example: Simplify √192 = √64•√3 = 8√3 Simplifying Radicals Example: Simplify √192 = √64•√3 = 8√3
