Fermat's theorem sum of two squares
WebMar 24, 2024 · In 1636, Fermat stated that no integer of the form is the sum of three rational squares, and in 1638, Descartes proved this for integer squares. In 1658, Fermat subsequently asserted (but did not prove) that , where is any prime of the form (i.e., any prime of the form ) is the sum of three squares. WebTheorem 4.1.5 (Fermat). Let p be prime.
