Similarly, Baudhayana discovered that "x" = 17, "y" = 12 and "x" = 577, "y" = 408 are two solutions to the Pell equation, and that 17/12 and 577/408 are very close approximations to the square root of two.
Če sta "x" in "y" pozitivni celi števili za kateri velja enačba, potem je ulomek "x"/"y" racionalni približek √2.
