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. 3.

|dw:1349987270081:dw| could help explain this one too?

6. Venomblast Group Title

im sorry the answer is $4\sqrt{10}/5$

7. Venomblast Group Title

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

simplify it. and you will get $3+\sqrt{2}$

$\sqrt{x-2}-4=0$

12. Venomblast Group Title

add 4 to both side.then square both side

13. Venomblast Group Title
