Math b question and solution

I am currently in a math class called math b. We are learning about radicals and below i will explain how to solve a radical. 1. Find to factors of radical 18 one being a square root. 2. simplify whats in the radical by putting the square root of that square root factor on the outside of the factor. 3. Your answer is 3 radical 2 because radical 2 cannot be simplified any more. That is my math b problem.
