We apply a deep result of Bilu,Hanrot and Voutier on primitive divisors to show that if the class number of quadratic field Q((-b)~(1/2))is a power of 2,then,the Diophantine equation x~2 + b~y=c~z has only the positive integes solution (x,y,z)=(a,2,5)with min(x,y,z)>1.

利用Bilu,Hanrot and Voutiers关于本原素除子的深刻结果证明了:如果二次数域Q((-b)~(1/2))的类数是2的方幂,则丢番图方程x~2+b~y=c~z仅有正整数解(z,y,z)=(a,2,5)适合min(x,y,z)>1。

In this paper,we firstly modified the mistake in reference of Bennett,then using Strmer s theorem of the solutions of Pell equation,and a deep result of privitive divisor of Bilu,Hanrot and Voutier,we proved that there is no exist four distinct triangular numbers in geometric progression,therefore we sovled the question of Sierpinski on triangular numbers.
