# I Can't....Can Anybody else?

I have two problems-

1.Find all primes $$p$$ such that there are positive integers $$a$$ and $$b$$ for which $$p=a^{2}+b^{2}$$ and $$a^{2}+b^{2}$$ divides $$a^{3}+b^{3}-4$$.

2.Find all natural numbers $$n$$ and $$k$$ such that $$2^{n}+3=11^{k}$$.

Hey @Souryajit Roy , I got the answer for problem 2. The only solution is $$(3,1)$$. I will post the solution soon. It's very easy.

Sorry, I lost the paper on which I wrote the solution. And I forgot the way I proved it as it is too long. Sorry :(
