haha ive done stuff like this before, where i know i got all the others right and i dont "need" the points for a question. this one is really clever though, better than anything i ever came up with

That is just stupid. Yeah it`s "cute" but you know it won`t go over with a teacher. You only do that if you`re a dumbass who doesn`t know the answer or you`ve got an A nailed down so hard that you can afford to miss some.

LOL smooth LandoGriffin. Sadly we all saw your first incorrect attempt at being a smug prick (just after Angelmassb`s correct answer), before you deleted it and replaced it with the actual answer just there.

The lesson here, Lando, is that if you`re wrong, be a man and own up to it. Don`t go scurrying away looking up the correct answer, and then trying to hide the evidence of your own stupidity.

Are you making fun of me for correcting a mistake?

Really?

I even cited my source (wikipedia) which is an admission that I looked up the answer. It is not "stupidity" to look up a correct answer when one makes a mistake and then to correct the mistake. It is making a correction. What sort of insecure freak are you to make fun of someone for correcting a mistake?

Yeah, so I was pretty close with my first guess, I had everything except the formula for the coefficient, which I had to look up because I couldn`t remember it off the top of my head. It has been about 18 years since I learned this stuff. I even cited my source (wikipedia) to show that I had to look up the binomial coefficient, what is wrong with that? I have to say I was pretty damn close for someone who hasn`t done any math for almost 20 years, except estimating odds in craps and blackjack.

So, yeah, what`s-her-name wasn`t even close, but I was extremely close and just had to look up the formula, which this student would have been given in class.

I mean, who else around here cites their source when they look things up?

"your first incorrect attempt at being a smug prick"

Solving a math problem is being a smug prick? You have issues, Bob, seriously. My first incorrect attempt was at solving a math problem. Then I corrected it. That`s all.

If the kid could prove to me they knew how to actually do the problem (like on the board lets say...in front of the class) I would actually give him EXTRA credit for creativity! then again, it`s prolly a good thing I`m not a teacher... lol

Hey guys, nobody cares what the answer really is. Mmk?

And I`d rather have my students get the right answer, proving that I actually taught them something, than have them make up some smart-ass crap like this.

"DAMN LANDO> O.o i`m seeing that as made up, i don`t know where the hell you got the k and what the exclamation marks represent"

I didnt actually solve the problem to see if he was right, but I can tell that isn`t completely made up. "K" is the counter, and the exclamation marks denote factorals. (e.g. 4! = 1*2*3*4. n! = 1*2*3*....*n-1*n.) Gah, I hate series.

and lando is right K is a constant that is yet unknown and the ! is a known mathmatical term it means you take that number (n) and multiply it by all the numbers before it. for example if n=5 it would be 5x4x3x2x1 =120 but I just have a BA in mech engineering what do I know

"and @ fibericon... I have never seen it before cause I don`t have time to "surf" all the lame sites you do, thats why I come here."

Hur hur, you don`t know what the internet is so I don`t have a life. I love it when people who need a compass and three personal aids to find their power button say things like that.

- You can`t blame the kid for his answer, he gave his teacher what she was asking for.

MUAHAHAHAHA.

n_n

What about this one?

a^n + n a^(n-1) b + n(n-1)/2! a^(n-2) b^2 + ... + b^n

Wow, no it is not, you are not even close.

a^n + n(a^(n-1)b) + n!/(2(n-2)!) (a^(n-2) b^2) ...n!/(k!(n-k)!) (a^(n-k)b^k)... n!/2(n-2)! (a^2 b^(n-2)) + n(a b^(n-1)) + b^n

The question is asking for the binomial coefficient, which is n!/((k!)(n-k)!)

http://en.wikipedia.org/wiki/Binomial_co...

a^n + n(a^(n-1)b) + n!/(2(n-2)!) (a^(n-2) b^2) ...n!/(k!(n-k)!) (a^(n-k)b^k)... n!/2(n-2)! (a^2 b^(n-2)) + n(a b^(n-1)) + b^n

The question is asking for the binomial coefficient, which is n!/((k!)(n-k)!)"

NEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEERRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRD

SUPER NERD!!! *crashing applause*

DAMN LANDO> O.o i`m seeing that as made up, i don`t know where the hell you got the k and what the exclamation marks represent

For the record, your initial response was this:

"the actual answer is a^n+b^n."

Wow, no it is not, you are not even close.

a^n + a^(n-1)b + a^(n-2)b^2 + ... + ab^(n-1) + b^n

Because I WILL catch you.

The "k" is 1, then 2, then 3, then so forth until eventually you reach "n" which is given in the problem.

Gah, I hate series.

Multiply it out. It`s just the binomial theorem.

Uh, sry, math nerd here.

I hate math....

I had the Jupiter Jack ad on the side, and I just hear Billy Mays voice start yelling. I thought I was going crazy.

That was all win.

XD

Ironic much? It`s old, but you saw it recently. Hmmm...

Hur hur, you don`t know what the internet is so I don`t have a life. I love it when people who need a compass and three personal aids to find their power button say things like that.

I actually opened up this piece of spam..... it was not interesting at all. Sir/Madam, I accuse you of untruths!

But still funny :P

haha
