Let a, b, c be pairwise relatively prime positive integers such that \(a^2 + b^4=c^2\) and b is odd. Then we show that the equation of the title has only one positive integer solution \((x, m, n)=(a, 4, 2)\) under some conditions.

设a , b , c为成对互质正整数,使得\(a^2 + b^4=c^2\)和b为奇数。然后我们证明题目的方程在某些条件下只有一个正整数解\((x, m, n)=(a, 4, 2)\)。
