Nice.
How do you show it when n is divisible by 15?

Well for starters, if n^4 + k is not even, then there is a chance that it might be a prime.

That is rather easy to achieve, since n^4 is always even.

What? Why choose 14, why not 2. n^4 is not always prime.
You're an idiot.

n^4 is not always even, what I meant.
The other is also true, but rather irrelevant.

both incorrect.
1. x^4 is x^2 * x^2.
2. x^2 is always even.
3. let y = x^2
4. then x^2 * x^2 = y^2
5. see 3

I know, read
>>10, also the statement "n^4 is not always prime" is still true. I meant even though

Not always prime implies it's at least once a prime.
So it's false.

2. x^2 is always even.
I can understand making that mistake once, if you're drunk, but twice? Exponentiation is not multiplication.
n % 2 = n^4 % 2
ALWAYS >>15
You're a fucking idiot. lrn2logic.

He meant the two don't behave the same. e.g. while x*2 is always even, x^2 is not (so long as x is an integer).

Fail.
x=0

Er, "not always" doesn't imply "is once".
Maybe linguistically, but strictly logically, no.

Uh, no. 1 is an integer, 2 is an integer, integers are closed under field operations. Hence 0.5 is an integer.

The integers are NOT closed under field operations because they do not form a field. They are a group under addition, but that is not sufficient for defining a field. You're thinking of the rationals.
