This topic introduces some concepts of radical expressions with variables and begins to show how to solve radical equations. This series of seven lessons describes how to multiply and divide radical expressions that contain variables. The student will also learn how to solve radical equations.
Also, important concepts of rational exponents are described in this topic.
This lesson teaches students how to multiply radical expressions that contain variables.
This lesson shows the student how to divide radical expressions that contain variables.
In this lesson, the student is introduced to basic radical equations. The student learns how to solve these types of equations. The lesson also shows examples of extraneous solutions to show the student the importance of checking solutions.
This lesson shows the student how to solve radical equations with more than one radical.
This lesson teaches the student how to solve radical equations with more than one radical that are more complex than the previous lesson.
In this lesson, the student learns the definition of rational exponents. The multiplicative property of exponents is used to describe why rational exponents lead to roots.
This lesson teaches the student how to handle negative rational exponents. The student is shown how the negative exponent can be rewritten with a positive exponent in the denominator and then treated as in the previous lesson.
