9:10 – 9:15

Properties of radicals

if n is a positive even integer

if n is a negative even integer

For example, and

9:15 – 9:20

Example 1) Simplify each expression by using the properties of radicals

9:20 – 9:30

Practice: simplify each expression

9:30 – 9:33

Product and Quotient Properties of Radicals

For a ≥ 0 , b ≥ 0 , and positive integer n:

and

9:33 – 9:40

Example 2) Simplify each expression.

what did I do here?

9:40 – 9:50

Practice: simplify each expression

9:50 – 10:00

Example 4) Simplify each sum of difference

its possible to do 10
* 5 but none of those would square

10:00 – 10:10

Practice: simplify each sum or difference

10:10 – 10:17

Example 4) Simplify each product

10:17 – 10:22

Example 5) Write each expression with a rational denominator

10:22 – 10:26
