    Assignment:Find the solution set of inequality (30000/420K)^2+(30000000/(46667K+70K^2))^2 <100^2 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 30000 / 420 * K ) ^ 2 + ( 30000000 / ( 46667 * K + 70 * K ^ 2 ) ) ^ 2 <100 ^ 2         (1)
        From the definition field of divisor
         46667 * x + 70 * x ^ 2 ≠ 0        (2 )

---

    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)：
         K < 0 或  K ＞ 0

---

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