Am i a genious or a complete idiot?

A Friend of mine once told me:

2x(root2)

and as 2 = (root2)x(root2)

then 2x(root2) = (root2)(root2)(root2) = 3(root2) !!!!

HOWS THIS POSSSIBLE?????

The first part of what I said:
Candy-Kills said they were a genius. This means they are extremely intelligent, not just in one subject, but in all subjects, therefore spelling shouldnt be a problem.

Since when was the definition of a genius "Someone who excels in all subjects"? I'd bet my right ear that Beethoven couldn't do maths to save his life, that Einstein couldn't write for toffee, and Shakespeare wouldn't have the first clue how to write a symphony.

hmm youre applying for maths???

ok lets do a bit of revision

x + x + x = 3x

and

(x)(x)(x) = x^3

therefore

(root2)(root2)(root2) is not = to 3(root2) but simply (root2)^3 = root 8

good luck for your interviews ....

cexy, i know you are a bit of a genius though

you're absolutely right! cexy, i know you are a bit of a genius though, and wondered if you could help out this guy called superkillball with his fluids work. he's started a thread below entitled 'fluid mechanics, help!', because i'm not terribly good at fluids so can't help him, and i've seen some of the solutions you've done before, and they're generally very good.

Relating back to the original posting, could (root2)(root2)(root2) ever equal 3(root2) under some form of a group? It's a longshot to be honest. Me and my friends were wondering if 2 + 2 could ever equal 5 under a certain but unfortunately not due to the modulo arithmetic

2+2=5

But that's definitely cheating

ok, but don't tell me it didn't struck u all the first time u saw it?

it did to me... (that was 4 years ago.. but still)

besides, maybe u arent aware of this but people is spain are really short, plz feel a little sympathy 4 me at least!

since when the knowledge of MATHS depends on the knowledge of ENGLISH?
also : One would assume a person of extraordinary intellect could know that the first language of people from Spain is not English... making a spelling mistake doesnt have ANYTHING to do with whether he/she is good at math or not!
besides, i bet that if he/she wrote the question in spanish, you wouldnt be able to give that "comment"... and yet: i bet if u had to answer that question in Spanish... you would had alot of mistakes.

Not if you're using the Gamma function as your factorial operator. That is defined for all complex numbers, though it is singular for negative integers.

It has the relation $\Gamma(z+1) = z\Gamma(z)$, the usual factorial property, and for positive integers it is the factorial function.
