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

---

    From inequality(1)：
         a ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(2)：
         a ＞ 0

---

    From inequalities (1) and (2)
         a ＞ 0    (3)

---

    The final solution set is :
         a ＞ 0
