Abstract:   Let r be an odd integer with r > 1 , and let u, v be positive integers such that 2 | u gcd ( u, v ) and u > 2r v????, Further let a, b, c be positive integers satisfying a + b - 1 = ( u + v - 1) r and c = u2 + v2 . The value of Jacobi symbol ( b/ v ) / ( a/ u) is determined. This result can be used for solving the exponential diophantine equation ax+by=cz

Key words: Exponential diophantine equation, number of solutions, Jacobi symbol
