EQUATIONS CONTAINING VARIABLES UNDER ONE OR MORE RADICALS

Note::

- In order to solve for
*x*, you must isolate*x*. - In order to isolate
*x*, you must remove it from under the radical. - If there is just one radical in the equation, isolate the radical.
- Then raise both sides of the equation to a power equal to the index of the radical.
- With these types of equations, sometimes there are extraneous solutions; therefore, you must check your answers.
- If the index of the radical is even, many times there will be a restriction on the values of
*x*.
