Abstract: Let m,r be positive integers such that 2|m,2r and r>1.let Ur,Vr be integers with Vr+Ur-1=(m+-1)r.Further let a,b,c be positive integers such that a=|Vr|,b=|Ur| and c=m2+1.It is proved that if b≡3(mod 4),and b or c is a prime,then the equation x2+by=cz has only the positive integer solution (x,y,z)=(a,2,r).

Key words: exponential diophantine equation, number of solutions, upper bound
