When what you mean is “X[sup]2[/sup]” which is the correct English: “X square” or “X squared”?
X squared. “Squared” is being used as a verb.
“X squared” is correct.
“X square”= two consecutive nouns
“X squared”= noun (being x) followed by a verb (squared).
X is a variable, and the ^2 is the process (verb) of multiplying x by itself.
Bastid, beat me to it…
Sob. They’re going to make me change my user-name, [symbol]P[/symbol][sup]2[/sup], because of some technical problems.
Thanks. Somehow something like “Pi squared” just won’t seem the same: No pizzazze. 
So, any chance that the secret of Capital Pi will be declassified anytime soon? Why can’t you tell us the significance?
No. Because.
No.
But, on second thought, about your second question, rsa: If you answer my highly-embarrassing, posted-while-very-red-faced question which is even now sliding off the page below, I will undertake the project required to see if perhaps I can give a hint or more about why I can’t tell you the significance of what-I-had-thought-to-be an innocuous SDMB-user-name. 
OK.
Unusual? NO
Dangerous? NO
I didn’t even bump the thread that’s causing your embarrassment.
To the OP, I’ve gotten kinda used to Parameter & #928;& #178;, but there’s nothing wrong with Pi squared.
Too late, too late, rsa. Choosybeggar beat you to the answer–and I now regret having ever made the pact.
Still: What is a poster if their word is little more than a patch of slippery algae. I will attempt to embark on the project needed to see if I can give a hint to the answer to your second question.
Thanks for your support but none other that TubaDiva has issued a decree. I need to figure out how to be sure that the “Pi” looks like a “Capital Pi” without demanding any thought.
Sorry, rsa, but my project ended in failure–almost as soon as it began. :eek:
It did produce some interesting suggestions for my new user-name: Loose Lips, Ship Sinker and, promoted as being most appropriate, Blithering Blabber Mouth.
It was also suggested that I stop posting to the SDMB altogether.
Well thanks for trying. Although now we know that it’s not just you apparently, but a conspiracy involving multiple people. I was just trying to decide if I should report you to the FBI or crankdotnet or blackmail you for a piece of the pie (ha). I guess I’ll just chalk it up to the Illuminati for now.
I think that you might have things exactly backwards as to the “whom.” For now, the word, I reckon, is “Shhhh.”
Capital Pi? White House!!! Get it?
This thing goes all the way to the top, baby.
