    Assignment:Find the solution set of inequality 200*0.07*0.07*0.07/（3*71*1000000000*1/12*0.016*d*d*d） <0.035-d/2 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        200 * 0.07 * 0.07 * 0.07 / ( 3 * 71 * 1000000000 * 1 / 12 * 0.016 * d * d * d ) <0.035 - d / 2         (1)
        From the definition field of divisor
         3 * 71 * 1000000000 * 1 / 12 * 0.016 * x * x * x ≠ 0        (2 )

---

    From inequality(1)：
         d < 0.069999
    From inequality(2)：
         d < 0 或  d ＞ 0

---

    From inequalities (1) and (2)
         d < 0 或  0 < d < 0.069999     (3)

---

    The final solution set is :
         d < 0 或  0 < d < 0.069999
