What is the first step to solving Radical Equations?

• Check for extraneous solutions.

• Raise each side of the equation to the power of the index.

• Isolate the radical on one side of equations.

• Solve the remaining equation.

How would we say this if converted to radical form?

• "Thirty-two to the three-fifths"

• "Fifth root of thirty-two raised to the third power"

• "Third root of thirty-two raised to the fifth power"

• "Quintic root of thirty-two raised to the fifth power"

• "Thirty-two and three-fifths"
