    Assignment:Find the solution set of inequality 60000/(3.14*d^2)+6*32000/(3.14*d^3) <35000000 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        60000 / ( 3.14 * d ^ 2 ) + 6 * 32000 / ( 3.14 * d ^ 3 ) <35000000         (1)
        From the definition field of divisor
         3.14 * x ^ 2 ≠ 0        (2 )
        From the definition field of divisor
         3.14 * x ^ 3 ≠ 0        (3 )

---

    From inequality(1)：
         d < -0.000068 或  d ＞ 0.12195
    From inequality(2)：
         d < 0 或  d ＞ 0
    From inequality(3)：
         d < 0 或  d ＞ 0

---

    From inequalities (1) and (2)
         d < -0.000068 或  d ＞ 0.12195    (4)
    From inequalities (3) and (4)
         d < -0.000068 或  d ＞ 0.12195    (5)

---

    The final solution set is :
         d < -0.000068 或  d ＞ 0.12195
