Transcript of Warm Up. Algebra 3 Chapter 7: POWERS, ROOTS, and RADICALS Lesson 2: Properties of Rational...
Warm Up
• Evaluate• 1. • 2.
Algebra 3Chapter 7: POWERS, ROOTS, and
RADICALSLesson 2: Properties of Rational
Exponents
VOCAB
• Like Radicals – when 2 terms have the same index
Today
• Today we will learn how to simplify rational expressions to make them easier.
Properties• add exponents• multiply exponents• distribute exponent• change the spot and make power
opposite• subtract exponents• distribute exponent
Directions
• Combine Like radicals• Find a property that looks like the problem
and do what the property does.
I DO (Simplifying)
• Simplify the expression• 1. • 2. • 3. • 4.
WE DO (Simplifying)
• Simplify the expression• 1. • 2. • 3. • 4.
YOU DO (Simplifying)
• Simplify the expression• 1. • 2. • 3. • 4.
REVIEW
• What did you learn?
Homework
• Worksheet– 7.2B (1 – 9)
Warm Up
•Simplify•1. •2.

Today
• Yesterday we learned how to simplify rational expressions to make them easier.
• Today we are doing the same thing but with variables.
Properties• add exponents• multiply exponents• distribute exponent• change the spot and make power
opposite• subtract exponents• distribute exponent
Directions
• Combine Like radicals• Find a property that looks like the problem
and do what the property does.
LETS TALK
• What does the following mean?
Logic
• ???• ???
• What can I determine about radicals and variables?
• When I have a ___ root and a bigger power of a variable underneath the root, I will _______ the ________
I DO (Simplifying with Variables)• Simplify the expression• 1. • 2. • 3. • 4.
WE DO (Simplifying with Variables)• Simplify the expression• 1. • 2. • 3. • 4.
YOU DO (Simplifying with Variables)• Simplify the expression• 1. • 2. • 3. • 4.
REVIEW
• What did you learn?• How is this different from what you learned
yesterday?

Today
• The past 2 days we learned how to simplify radical expressions
• Today we are going to learn how to combine like radical expressions
Directions (Add and Subtract)
• Find like radicals• Make the radicand be the same number• Perform the given operation to ONLY the
outside number
I DO ( Like Radicals)• Simplify the like radicals• 1. • 2. • 3. • 4.
WE DO ( Like Radicals)• Simplify the like radicals•1. •2. •3. •4.
YOU DO ( Like Radicals)• Simplify the like radicals• 1. • 2. • 3. • 4.
Question
• What if the powers aren’t the same?
REVIEW
• Today we learned how to combine like radicals
Homework
• Worksheet– 7.2B (25 - 30)
