[ 1/1Inequality]
    Assignment:Find the solution set of inequality 162.86ln（16x）/x ≤5 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        162.86 * ln ( 16 * x ) / x ≤5         (1)
        From the definition field of ln
         16 * x > 0        (2 )
        From the definition field of divisor
        x ≠ 0        (3 )

---

    From inequality(1)：
         0 ≤ x ≤ 0.06262
    From inequality(2)：
         x ＞ 0
    From inequality(3)：
         x < 0 或  x ＞ 0

---

    From inequalities (1) and (2)
         0 < x ≤ 0.06262     (4)
    From inequalities (3) and (4)
         0 < x ≤ 0.06262     (5)

---

    The final solution set is :
         0 < x ≤ 0.06262
