Is It Irrational?

Made a new page: Is It Irrational?

It only deals with square root irrationalities, though.

Re: Is It Irrational?

The is a neat way of discovering if the square root of a number is irrational or not.

The is a typo in that sentence.

Re: Is It Irrational?

The page is very good.
I feel it should include irrational numbers of greatest importance in mathematics, namely pi, e and phi.

Re: Is It Irrational?

I talk about them on the general page on Irrational Numbers, but provide no discussion on why they are irrational (which I should).

ALSO, I have the awkward 2[sup]2[/sup]/1 = 2[sup]2[/sup]/1[sup]2[/sup] ... which should be reduced to 2[sup]2[/sup] ... but then it doesn't look like a rational number.
