Best ResponseYou've already chosen the best response.0sure, first do you know how to simplify sqrt(18) and sqrt(8)?

Best ResponseYou've already chosen the best response.0yes i simplified the problem to \[3+3\sqrt{2}/1+2\sqrt{2}\]

Best ResponseYou've already chosen the best response.0when you have a square root in the denominator, to clean it up you have to multiply by something called the conjugate, which basically just means you change the sign of the square root term

Best ResponseYou've already chosen the best response.0so for this case, you would multiply it by (12sqrt(2))/(12(sqrt(2))

Best ResponseYou've already chosen the best response.0\[12\sqrt{2}\] right?

Best ResponseYou've already chosen the best response.0right, so did you multiply the top and bottom by that?

Best ResponseYou've already chosen the best response.0what confuses you about the bottom part? what did you get for the top?

Best ResponseYou've already chosen the best response.0i got \[36\sqrt{2}+6\sqrt{2}12\] simplified to 9

Best ResponseYou've already chosen the best response.02sqrt(2)*3sqrt(2) is what?

anonymous

Best ResponseYou've already chosen the best response.0well no, that is 12, but you got that part right, your mistake was 3sqrt(2) * 1 i believe

Best ResponseYou've already chosen the best response.0oh your right... i thought i was going to be able to eliminate the roots in the middle...

anonymous

Best ResponseYou've already chosen the best response.0you want to eliminate the roots on the bottom, that's why are we doing this. you don't have to eliminate the roots on the top.

Best ResponseYou've already chosen the best response.0\[36\sqrt{2}+3\sqrt{2}\] 12 right?

Best ResponseYou've already chosen the best response.0looks good for the top

anonymous

Best ResponseYou've already chosen the best response.0not in my math capabilities thats for sure haha. \[93\sqrt{2}/7\]

anonymous

Best ResponseYou've already chosen the best response.0okay so the numbers are right but my text book says all the nubmer are positive.

anonymous

Best ResponseYou've already chosen the best response.0looks good, don't forget parentheses if you write it like you typed it, and you can multiply by 1/1 and get rid of all the negatives if you want

Best ResponseYou've already chosen the best response.0parentheses? the ones used to foil? and okay thank you soo much your very helpful.

Best ResponseYou've already chosen the best response.0i was just saying the way you typed your answer, could be 9  (3sqrt(2)/7) which is not the same thing
