For positive integers n, we have that floor(n^2/3) is a prime number.

Your conjecture holds until 8
Very unimpressive
back to work, mochi-san
>>8685568
This is fucking retarded
>>8685573
you don't even need to go up to 8
it fails at 5 and if you don't want to do computations it's immediate that it fails for 6
*For what positive integers n, we have that floor(n^2/3) is a prime number, sorry.

>implying 2 and 3 are not prime numbers
u w0t m8
we're talking about the cube root of n squared, not n squared divided by 3

I see no parenthesis there and from this post sequence I assume you are not the OP so why don't you shut the fuck up.
For positive integers n, the nth prime number is prime.

1 is not a prime
for positive numbers x, we have that f(x)=5 yields a prime number

11*3
WEW lad
I tried it for x=2, 3, 4.
By induction it's true.

3 you fucking idiot.
3^2/3 = 2.08
⌊2.08⌋ = 2
[math]\left \lfloor {x^{\frac{2}{3}}} \right \rfloor\ \text{is prime} \implies x^{\frac{2}{3}} \in\bigcup\limits_{p\ \text{prime}}[p,p+1)\\ \implies x \in \bigcup\limits_{p\ \text{prime}}[p^\frac{3}{2},(p+1)^\frac{3}{2}) [/math]
>>8685661
I don't get it.
>>8686064
Never mind.
>>8685674
he did it
he solved the primes
noble piece price
>>8685871
The way he wrote it, it's actually [math]\frac{x^2}{3}[/math] and not [math]x^{\frac{2}{3}}[/math]
