| Abstract: |
| In this paper, we study the solution of the exponential Diophantine equation 4x + by = (b + 4)2. Let b be a fixed odd positive integer with b > 1, using some known results on exponential Diophantine equations and an extension of the stormer theorem on Pell's equations, we prove that the equation 4x + by = (b + 4)2 has only the positive integer solution (x, y, z) = (1, 1, 1). |
