I need help to understand what I found Looking at the primes of the form k^n*(k^n+1)+1 if found that for k and n > 1 a prime of this form exist only when n is...
... The correct argument is then as follows: If n = 3^m*s with s > 1 and coprime to 3, then N is divisible by y^2 + y + 1, with y = k^(n/s) and cannot be...

... Let x = k^n. Then your target is N = x^2 + x + 1 = (x^3 - 1)/(x - 1) = (k^(3*n) - 1)/(k^n - 1) Now observe that k^(3*n)-1 is divisible by the cyclotomic...
Hope all doing well. I need to know a way to find nth Fibonacci number,where n may be vary large(say 2^100 ). If I use the expression F(n) = i/sqrt(5) {...

What do you mean by "find"? To find decimal representation? If so, note that 2^100-th Fibonacci number has 264923307603166815904318992952 = 2.64923*10^29...
