Question

I need a reminder of how to do these.. I need to rationalize the denominator.

1/sqrtof6

Answer 1

\[1/\sqrt{6}\]

Answer 2

a reminder hmm...first step is to look at your denominator..make sure it's just one term consist of square root

Answer 3

Yes, I know it cannot be a square root, but I forget how to turn it into a real number. Do I take the sqrt of 6 and times the whole thing by 2?

Answer 4

Or do I multiply the sqrt of 6 to the top and bottom?

Answer 5

multiply sqrt 6 to top and bottom

Answer 6

So it would be \[\sqrt{6}/6?\]

Answer 7

yes

Answer 8

So that would apply with any sqrt as a denominator? Thank you.

Answer 9

as long as it doesn't look like this \[\frac 1{1 + \sqrt 6}\]
if it looks like that, then that's another story
