Their work established that the equation has the two non-negative integer solutions: (1, 0, 3) and (1, 1, 13). Our findings reveal an additional solution, (2, 1, 15), and we show that these three solutions constitute the complete list of non-negative integer solutions for this equation. This extends and completes the main result presented in their paper.MathematicsComputer ScienceArticleSCOPUS10.69793/ijmcs/01.2025/panraksa2-s2.0-8520064828718140432
