    Assignment:Find the solution set of inequality 20*x*lg(x)-23*x+3 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        20 * x * lg ( x ) - 23 * x + 3 >0         (1)
        From the definition field of lg
         x > 0        (2 )

---

    From inequality(1)：
         x < 0.063998 或  x ＞ 13.775621
    From inequality(2)：
         x ＞ 0

---

    From inequalities (1) and (2)
         0 < x < 0.063998 或  x ＞ 13.775621    (3)

---

    The final solution set is :
         0 < x < 0.063998 或  x ＞ 13.775621
