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.
