No, because 4 and 2 are the only two even digits that appear exactly 2 times, of course.
Though, what you said might be another reason for it.
#602 Re: Puzzles and Games » replace the question mark » 2014-09-04 20:53:11
You should know why.
#603 Re: Puzzles and Games » replace the question mark » 2014-09-04 20:39:38
I think it might be 42.
#604 Re: This is Cool » i = i^x mod 4 » 2014-09-03 05:28:32
That is not much of a surprise, since 0.02th root of i is 50th power of i. No need for for modulo to get involved.

That's the same thing as the last one.
#609 Re: This is Cool » Find all the prime numbers in a given range.... » 2014-08-27 05:56:26
That is incorrect. For example, 25 would remain after the process, but is not prime.

Hi PatternMan
Do you remember how the absolute value of a number is defined?

Hi iluvdogs
Welcome to the forum!
What is your favourite fur color?
That said, I think both of you have asked incorrect questions.

Hi Mark
I'm getting 13 for the 2D case.
#615 Re: Help Me ! » I have proved Goldbach's theorem can someone check it for me? » 2014-08-16 21:34:19
I don't think "proving it" probabilistically does not actually prove it, just shows it's true in many cases, unless I'm missing something.

Assuming y is the number of cubes, the formula is y=e^3/x^3.

I'v also had that problem with the word "p.o.k.e.r".

The first and third one are plays on familiar and cheesy pickup lines.

You cannot upload pictures, Shivam.
#622 Re: Help Me ! » Derivative of Ln(x) » 2014-08-01 05:07:51
Is there any way you could post a picture of that or maybe use LaTeX?
#623 Re: Help Me ! » Derivative of Ln(x) » 2014-08-01 02:48:31
Hm, it's all mixed up. How is 1/ln(g) * ln(x) = (1/ln(g)) * (1/x) ?
#624 Re: Jokes » Math Pick-up Lines » 2014-07-31 10:23:15
That doesn't mean it does not have meaning.
#625 Re: Jokes » Math Pick-up Lines » 2014-07-31 06:21:03
The number 3 does not exist either, then.
