Lesson 1.3: Radical Expressions and Equations

This final lesson relates all the skills of radicals to equations that many math-related professions use on a daily basis. For instance, electrical engineering formulas, such as the voltage formula , where P is the power in watts and R is the resistance in ohms, are realistic applications of radicals.


In Lesson 1.3, you will learn how to

  • apply your understanding of radical expressions to equations
  • solve problems involving radical equations
