E769  Solutio problematis Fermatiani de duobus numeris, quorum summa sit quadratum, quadratorum vero summa biquadratum, ad mentem illustris La Grange adornata
(A solution to a problem of Fermat, on two numbers of which the sum is a square and the sum of their squares is a biquadrate, inspired by the Illustrious La Grange)
Summary:
Euler returns to the problem, motivated by Lagrange, of finding x and y such that x + y is a square and
xx + yy is a fourth power. This is a very short paper.
