Homework Help: Calculus-Rationalizing Denominator

Posted by -Untamed- on Monday, October 3, 2011 at 9:34pm.

I am very confused on how to rationalize a denominator, it just gets harder and harder.*will be using the V symbol again as a square root symbol.* I get how to rationalize something simple as V2/V7, I would get V14/7 as the answer, but I get confused on how to solve 1/V6 +2, this is the way I did it, and I know it's wrong.

1/V6 + 2 * V6 - 2/V6 - 2
1V6-2/V36 - 4
1V6 - 2/6-4
1V6 - 2/2

I don't get how to solve from here, would the 2's cancel out? and I'm left with 1V6.

And this is an even harder one...
V30 + 3V3/V30 - 3V3
