    Assignment:Find the solution set of inequality 5a-a*ln(a)-4 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        5 * a - a * ln ( a ) - 4 >0         (1)
        From the definition field of ln
         x > 0        (2 )

---

    From inequality(1)：
         0.757995 < a < 144.357226
    From inequality(2)：
         a ＞ 0

---

    From inequalities (1) and (2)
         0.757995 < a < 144.357226     (3)

---

    The final solution set is :
         0.757995 < a < 144.357226
