Answer:


36√(2)

Step-by-step explanation:

This radical can be simplified. You know that the number inside of the radical; 8, is the product of 4 and 2. You know that 4 is a perfect square (2 times 2). Therefore, you can leave the 2 on the inside and the 4 on the outside. You now must multiply the 18 on the outside of the radical by 2 because you must take the square root of the original 4 you had. Therefore, you answer will be
36√(2).
