rationalize the denominator
Is there any theorem saying that in below fraction we can't rationalize the denominator
2 π
I couldn't find any way and I don't think there is but I was wondering if this actually proved? for example for 1 2 we say
1 2 = 1 × 2 2 × 2 = 2 2
result have meaning if we look at fraction like Division

Are you speaking of rationalizing the denominator and the numerator at the same time? If not, a trivial solution would be 2 / π 1 , but that doesn't seem very interesting. So perhaps you are speaking about some sort of manipulation that creates 2 π = p q , where both p and q are rational. But, I would find that greatly disturbing, because then it would be the case that p q is also rational... in which case 2 π would be rational as well.
EDIT: Your example with 2 is similar to the trivial solution above, but, in the case of a radical, might have some more use.
So, yes, you can rationalize the denominator, if you find such action useful. But, would you, in the case of 2 π ?
