求：$x= ?$  $x^3$ （立方数）的最后四位数字是 $2024$ .

$$x=2500 k -1826, k \in N^{+}$$

蔡氏完全循环节问题

若 $2*10^n - 51$ 是素数，则 10 是这个素数的原根。

谢谢树新蜂老师提供100000以内的 n={2, 3, 4, 8, 11, 13, 17, 28, 56, 105, 231, 339, 643, 922, 1219, 1880, 2209, 4238, 4987, 14770, 56194, 67043, 96867}

任意指数，任意项，任意系数的高次不定方程，

除了 程中占，

我相信 Treenewbee 能够突破任意系数的不定方程！

蔡家雄

求：$x^{33}+y^{51}+z^{69}=w^{87}$

各指数除以3，两两互质，应该有解，，，，
