SECTION 7-3: SOLVING RADICAL EQUATIONS Solve equations that contain radicals or rational exponents

2
Solving Radical Equations Isolate the radical on one side of the equation, if necessary. Raise each side of the equation to the same power to eliminate the radical. Solve the resulting equation using techniques that you learned in previous chapters. Check your solutions.
