7. Fermat's Last Theorem - Wikipedia

   en.wikipedia.org/wiki/Fermat's_Last_Theorem

   Problem II.8 of the Arithmetica asks how a given square number is split into two other squares; in other words, for a given rational number k, find rational numbers u and v such that k 2 = u 2 + v 2. Diophantus shows how to solve this sum-of-squares problem for k = 4 (the solutions being u = 16/5 and v = 12/5). [29]
