Made a new page: Is It Irrational?
It only deals with square root irrationalities, though.
Comments, bug reports and suggestions please
"The physicists defer only to mathematicians, and the mathematicians defer only to God ..." - Leon M. Lederman
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.
The page is very good.
I feel it should include irrational numbers of greatest importance in mathematics, namely pi, e and phi.
It is no good to try to stop knowledge from going forward. Ignorance is never better than knowledge - Enrico Fermi.
Nothing is better than reading and gaining more and more knowledge - Stephen William Hawking.
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.
