This lively chapter begins with a lesson on simplifying square roots of whole numbers that are not perfect squares. From there you will handle how to simplify square roots involving variables raised to powers before learning to multiply radicals. Next stop involves mastering dividing square roots, which includes rationalizing the denominator. Then it is off to adding, subtracting, and using the distributive property with square roots. The next portion of the chapter takes you on a tour of the Pythagorean Theorem and Special Right Triangles. The chapter finishes with gusto as you learn about Trigonometry and how to apply it to real-world word problems. This is a truly powerful chapter full of exciting stuff connecting you to future courses of math studies! Time to rock it!
