OpenStudy (anonymous):

\[(3\sqrt{2}-2\sqrt{3})\div (3{\sqrt{2}}+2\sqrt{3})\] Basically you get rid of what is similar then for me personally I'll convert to decimal to make the adding and division easy and then basically use a calculator to convert back to the simplified form. :) If you don't have access to a calculator I apologize!

OpenStudy (anonymous):

I get 102 with 3√6 + 5√2 / 4√6-3√2 Is this right?

For the radicand on the denominator. 6 x 6 = 36 so with a square root, it's 6 and 6 times 4 is 24

OpenStudy (anonymous):
