Tabăra MathTime - Problema 6, Ziua II - JUNIORI
Rezolvați în $\Bbb{N}$ ecuația: $x^3+7=y^2$.
People are strange when you're a stranger,
Faces look ugly when you're alone.
Women seem wicked when you're unwanted,
Streets are uneven when you're down.

x^3+7=y^2 <=> x^3+2^3=y^2+1.Dar x^3+2^3 are un factor prim de forma 4k+3,care nu poate divide o suma de patrate.Ecuatia nu are solutii.
