Since 32 isn't a perfect square, you have to figure out what two numbers you can multiply to get you a product of 32. One of those numbers has to be a perfect square. Using 16 x 2 will get you the most simplified answer.
2√16 x 2
The square root of 16 is 4, so put that outside of the radical and multiply.

2 x (4) √2
8√2 is your answer.
That can be simplified to 8 times the square root of 2.
