Interactive Learning Adventure in Number Theory

šŸŽ“ What is Hensel's Lemma?

Hensel's lemma is a powerful technique in number theory that allows us to "lift" solutions from modulo p to modulo p^k. It's like having a mathematical elevator!

The Main Idea: If we have a root r of polynomial f(x) modulo p, and the derivative f'(r) ≢ 0 (mod p), then we can find a unique root modulo p² that reduces to r modulo p.

rk+1 = rk - f(rk) Ɨ [f'(rk)]-1 (mod pk+1)

This is essentially Newton's method in the p-adic numbers! Let's learn by solving problems together.
