you can split the the square root of 32 into \[\sqrt{16} and \sqrt{2}\]. square root of 16 is 4. so you will have \[4\sqrt{2}/\sqrt{5}. now we have a radical on the denominator. we dont want that. you will need to rationalize.

you will need to rationalize. so you multiply the denominator and numerator by \[3+\sqrt{2}\]
