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

---

    From inequality(1)：
         x < 1
    From inequality(2)：
         x ＞ -5
    From inequality(3)：
         x ＞ 0

---

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

---

    The final solution set is :
         0 < x < 1
