Which expression is equal to 9/3-sqrt 2

9/3 is 3, so an expression equal to the original one could be 3 sqrt 2. Another expression equal to the original one could be sqrt 18. This is because, within the square root, the 18 would break up into 9x2, allowing the 9 to be squared into 3. This would leave 3 sqrt 2 (or 9/3 sqrt 2).
