In this paper, we prove that the title exponential Diophantine equation has only the positive integer solution $ (x, y, z) = (1, 1, 2) $. As an another result, we show that if $ a = l $, then the title equation has positive integer solutions $ (x, y, z) = (n, 1, 2)...
y = x^n (power function), y = a^x (exponential function), y = log_a(x) (logarithmic function), y = sin(x) (sine function), y = cos(x) (cosine function), y = tan(x) (tangent function), and y = cot(x) (cosecant function). Each formula establishes the relation...
