    Assignment:Find the solution set of inequality （n-1000)^140/(n-1001)^140*(n-1)^150/n^150 >= 1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( n - 1000 ) ^ 140 / ( n - 1001 ) ^ 140 * ( n - 1 ) ^ 150 / n ^ 150 >= 1         (1)
        From the definition field of divisor
         x - 1001 ≠ 0        (2 )
        From the definition field of divisor
        x ≠ 0        (3 )

---

    From inequality(1)：
        The solution set is empty, that is, within the range of real numbers, the inequality will never be established!
    From inequality(2)：
         n < 1001 或  n ＞ 1001
    From inequality(3)：
         n < 0 或  n ＞ 0

---

    The final solution set is :
        The solution set is empty,that is, the inequality will never be estatlished within the real number range.
