This SAT Sphere lesson focuses on essential SAT test topics in the Radical Expressions and Equations section. You'll build a strong understanding of core concepts, learn time-saving test-taking strategies, and apply your knowledge to realistic Digital SAT practice questions.
01
Introduction to Radical Expressions and Equations
Explains why radicals matter on the Digital SAT and reminds students to recall exponent laws, factoring, and basic root skills from Roots and Radicals in Module 1.
02
Radical Notation and Key Vocabulary
Defines radicand, index, and nth‐root symbols while refreshing earlier work with square‐root notation and perfect squares.
03
Simplifying Single-Term Radical Expressions
Teaches prime-factor extraction (and variable exponents) to rewrite radicals in simplest form, extending prime-factor skills from Simplifying Algebraic Expressions.
04
Practice: Simplifying Radical Expressions
Gives scaffolded problems so students apply the factor-and-pull-out method immediately for mastery reinforcement.
05
Adding and Subtracting Like Radicals
Shows how to combine radicals by matching index and radicand, building on the combine-like-terms rule from Fundamentals of Algebra.
06
Practice: Add and Subtract Radicals
Provides targeted exercises that mix numerical and variable terms to solidify recognition of like radicals.
07
Multiplying, Dividing, and Rationalizing Radicals
Demonstrates product-and-quotient rules plus denominator rationalization, extending exponent-addition rules from Introduction to Exponents and Powers.
08
Practice: Multiply, Divide, and Rationalize
Offers mixed-difficulty problems so students automate rule selection under SAT timing.
09
Solving Radical Equations
Guides students through isolating radicals, squaring, and checking for extraneous solutions, refreshing linear- and quadratic-equation solving strategies.
10
Key Takeaways and Targeted Practice
Synthesizes all radical operations into SAT-style questions and highlights common pitfalls and time-saving checks.
