true or false ? opinions please !
what is the question?
I'm so excited.
Both.
Neither.
1. subst. - let p and k , two prime numbers greater or equal 2,from the set of prime numbers, P, in the form : p=2a + 1 and k=2b + 1 , such that a and b are natural numbers,from the set of natural numbers N, - let m=2n ,m greater or equal 4,even number,from the set of natural numbers N and n grater or equal 2,natural number from set of natural numbers N, 2. concl. - every even integer greater than 2 can be expressed as the sum of two primes 3. prove:- by ,,reductio ad absurdum” * - step 0. for n=2 --- m=4 --- 4=2+2 ** - step 1. for - if n is greater or equal 3 so always will be a number a and b such that n=a + b + 1 - prove. 3=1+1+1 4=2+1+1 5=2 +2+1 ................ n=a+b+ 1 - so for n=k than k=a+b+1 - suppose that is true - for k+1=(a+b+1)+1=(k)+1=k+1 - so for k+1 is true - for n grater than 2 always will be a number a and b such that n =a+b+ 1 *** - step 2. - every even integer greater than 4 can be expressed as the sum of two primes m=p+k - prove by ,,reductio ad absurdum" - so than m is not equal p+k - so than 2n is not equal 2a+1+2b+1 - so than 2n is not equal 2a+2b+2 / divide both sides by 2 - so than n is not equal a+b+1 - so what is in contradiction with the proof from step 1. where n=a+b+1 was proved that is true - so than m=p+k is proved that is true so,, every even integer greater than 4 can be expressed as the sum of two primes” --- q.e.d.
Woah, We are not going to do your homework.
true
This math is just too hard for you guys, stop making excuses and shut up!
then you do it for him
And he asked three questions simultaneously...
but its a true or false question and that made it really confusing for me
He actually didn't, you just can't read. He introduced the problem in 1, made a statement in 2 and he's trying to prove it in 3.
ok
Don't give up so easily guys. Give it a try.
Ok, you solve it for him, then. I don't know math theories thingy.
how much is understandably ?
yes sure just for people who know from what problem is the theme ,what conjecture ...
Phew. I got through it and it makes a lot of sense, it was just hard to understand, try to make your work more clear. Basically you prove that n can always be expressed as n=a+b+1. Then you use "reductio ad absurdum" to prove your point. Let's say that 2n≠p+k≠2a+1+2b+1. Then, 2n≠2a+2b+2, n≠a+b+1, which is impossible because you proved that is always true. Good work!
thank you @BluFoot ! so but you know what conjecture is proven here than in this case ?
so and this your words,reply mean that you accept this proof for seriosly true ?
yes wann being the Goldbach's conjecture
great thank you
Hmm, wikipedia says that there isn't actually a proof. Your proof looked pretty good but I guess it's not? not sure.
why ? in your first above reply you have told me that you have understood it very well and you say that is correct and acceptably true ?
so because this is an easy ,simple proof of by reductio ad absurdum
if the conjecture has been around since the 1700s, and it doesn't have a proof yet, i dont think there is going to be a "simple" proof for it. Also, if you want to verify if your proof is correct, you need to send it to an academic journal, so a referee can look at it.
ok thank you but do you can help me with this journal address ,email where i can sending it for deciding is true or false ,acceptably or not ?
im not too sure exactly who to talk to, but the Mathematics Association of America is a good place to start: http://www.maa.org/ Or the American Mathematics Society: http://www.ams.org/home/page
ok thank you very very much good luck bye
A book featuring the Goldbach's Conjecture http://www.amazon.com/Uncle-Petros-Goldbachs-Conjecture-Mathematical/dp/1582341281
well question is good but this would really involve much more time also.... i' ll get back if i find something useful
thank you
