What Happens If You Just Keep Squaring?

Start by squaring five again and again, and watch an endless number appear that is its own square. Discover why ten-adic numbers break down, how a prime base like three fixes the problem, and how p-adic numbers solve a puzzle from Diophantus with a surprising answer of negative one half. See why this strange idea mattered for Fermat's Last Theorem and the work of Andrew Wiles. #Math #PAdicNumbers #NumberTheory #FermatsLastTheorem #MathAndBeyond #LearnMath
