Use this chapter's video lessons to strengthen your understanding of rational roots. Review the steps involved in simplifying square roots, working with radical expressions and solving radical equations.

## Rational Roots - Chapter Summary

The short video lessons in this chapter will refresh, and perhaps improve, your skills in working with rational roots. Instructors guide you through a variety of problems, such as simplifying imperfect square roots and solving radical equations with two radical terms. You'll also study radicands, radical expressions and radical notation. In addition to being able to find a number's square root, you'll be able to do the following after watching the videos:

• Estimate square roots
• Simplify square roots and expressions with square roots
• Evaluate square roots of perfect squares
• Simplify square roots of powers in radical expressions
• Multiply and divide radical expressions
• Simplify the square roots of quotients
• Rationalize denominators in radical expressions

As you study rational roots, be sure to take advantage of the tools we offer with our lessons. The videos, developed by professional instructors, offer a jump feature in the timeline that you can use to rewatch explanations of concepts or example problems. We provide transcripts of our lessons as well and these highlight key terms for easy reference. Take the self-assessment quizzes included with all lessons to gauge your understanding of rational roots.
