Ch 20: ACT Math: Exponents

About This Chapter

Prepare for the ACT math test with our lessons on exponents. The short, motivating videos, followed by quizzes for self-assessment, will aid your review.

ACT Math: Exponents - Chapter Summary

Check out the lessons in this chapter on exponents in your review of algebraic fundamentals for the ACT. Our user-friendly video lessons revisit the following crucial topics:

  • Five properties of exponents
  • Simplifying expressions with exponents
  • Defining zero and negative exponents
  • Rational exponents
  • Simplifying expressions with rational exponents

After watching the video lessons, make sure that you work your way through the quizzes to see how you're doing. Go back to any concepts that still need more work. Your success on the math portion of the ACT may determine your placement in college-level courses.

ACT Math Objectives

Test questions concerning algebraic concepts make up 55% of the ACT math exam. The test addresses many of these topic areas:

  • Properties of square roots and exponents
  • Substitution for evaluation of algebraic expressions
  • Expressing functional relationships using variables
  • Understanding algebraic operations
  • Factoring
  • Rational and radical expressions
  • Sequences and patterns
  • Systems of equations

You'll have an hour to complete 60 multiple-choice questions within the math portion of the ACT, demonstrating your logic skills in solving math problems. All the problems are solvable with paper and pencil, and the test booklets have a space for you to write out your calculations. You may use approved models of calculators, however. Check with the ACT students' site for details. Your results will include an overall score, in addition to sub-scores for pre-algebra/elementary algebra, intermediate algebra/coordinate geometry and plane geometry/trigonometry.

Our video lessons will assist your review. Begin with the properties of exponents and then go over simplifying expressions and rational exponents. Take the self-assessment quizzes to find out if any areas still need more attention.
