first step would to be in getting the denominator from out of the radical by multiplying it by itself and whatever you do to the top you do to the bottom, so it becomes
3√8/√8 * √8 = 3/√8/8
√8 can be broken down to √4√2 and the√4 becomes 2 so you multiply the 2 and the 3 and you get 6
so it becomes 6√2/8 simplify your answer and it becomes 3√2/4
3√8/√8 * √8 = 3/√8/8
√8 can be broken down to √4√2 and the√4 becomes 2 so you multiply the 2 and the 3 and you get 6
so it becomes 6√2/8 simplify your answer and it becomes 3√2/4
