# 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 $2^{n}+3=11^{k}$.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

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.

Finally I solved it...no longer in need of a solution

Can you post the solution here? Plss

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 :(
