    Assignment:Find the solution set of inequality 900/(y)^2-108000/y >-4107793.367 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        900 / ( y ) ^ 2 - 108000 / y > -4107793.367         (1)
        From the definition field of divisor
         x ≠ 0        (2 )
        From the definition field of divisor
        x ≠ 0        (3 )

---

    From inequality(1)：
         y ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(2)：
         y < 0 或  y ＞ 0
    From inequality(3)：
         y < 0 或  y ＞ 0

---

    From inequalities (1) and (2)
         y < 0 或  y ＞ 0    (4)
    From inequalities (3) and (4)
         y < 0 或  y ＞ 0    (5)

---

    The final solution set is :
         y < 0 或  y ＞ 0
