Recall that a fraction indicates division, so if a radical is in the numerator of a fraction, your first step in solving would be to un-do the division- that is, multiply both sides by the denominator. The same is true if a radical is being multiplied by a fraction: to un-do multiplying by a fraction, you would divide by the fraction, which is written as multiplying by the reciprocal. Make sure that if you end with the square root of x is equal to some value, that you square both sides in order to find x.
