    Assignment:Find the solution set of inequality 4875000/((400+x)^2) <= 1.7 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        4875000 / ( ( 400 + x ) ^ 2 ) <= 1.7         (1)
        From the definition field of divisor
         ( 400 + x ) ^ 2 ≠ 0        (2 )

---

    From inequality(1)：
         x ≥ 1293.412844
    From inequality(2)：
         x < -400 或  x ＞ -400

---

    From inequalities (1) and (2)
         x ≥ 1293.412844    (3)

---

    The final solution set is :
         x ≥ 1293.412844
