<p><b>New page</b></p><div>This problem was given in [[Indian mathematics|India]] by the mathematician [[Brahmagupta]] in 628 AD in his treatise ''[[Brahmasphutasiddhanta|Brahma Sputa Siddhanta]]'':<br />
<br />
Solve the [[Pell's equation]]<br />
: <math>x^2 - 92y^2 = 1</math><br />
for [[integer]]s <math>x,y>0</math>.<br />
<br />
Brahmagupta gave the smallest solution as<br />
: <math>(x,y) = (1151,120)</math>.<br />
