Solving Radical Equations in One Variable

Objectives:

Solve square root equations in one variable algebraically.

Solve radical equations in one variable algebraically.

Solve equations containing variable expressions with rational exponents algebraically.

Solving Square Root Equations

Principle of Powers: If a = b then a = b.

Example:

Note: Always check your answers with the original equation if the exponent is even in order to determine which solutions are possible.
