[ 1/1Inequality]
    Assignment:Find the solution set of inequality ln（1+1/x）-1/1+x-1/√x（1+x） <0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ln ( 1 + 1 / x ) - 1 / 1 + x - 1 / √ x * ( 1 + x ) <0         (1)
        From the definition field of divisor
        x ≠ 0        (2 )
        From the definition field of ln
         1 + 1 / x > 0        (3 )
        From the definition field of √
        x ≥ 0        (4 )

---

    From inequality(1)：
         x < 3.02996
    From inequality(2)：
         x < 0 或  x ＞ 0
    From inequality(3)：
         x < -1 或  x ＞ 0
    From inequality(4)：
         x ≥ 0

---

    From inequalities (1) and (2)
         x < 0 或  0 < x < 3.02996     (5)
    From inequalities (3) and (5)
         x < -1 或  0 < x < 3.02996     (6)
    From inequalities (4) and (6)
         0 < x < 3.02996     (7)

---

    The final solution set is :
         0 < x < 3.02996
