• Solving Radical Equations A radical equation is an equation that contains radicals or rational  exponents Solve by: 1. Eliminate the radicals and obtain a linear or quadratic equation 2. Solve the linear or quadratic using your skills and strategies An important property to use when eliminating radicals is: If  a = b then an = bn If you raise one side of an equation to a power then you must keep  it equal by raising the other side to the same power.
