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

---

    From inequality(1)：
         x < -1.769713 或  x ＞ 0.769713
    From inequality(2)：
         x < 0 或  x ＞ 0
    From inequality(3)：
         x < 0 或  x ＞ 0
    From inequality(4)：
         x < -1 或  x ＞ 0

---

    From inequalities (1) and (2)
         x < -1.769713 或  x ＞ 0.769713    (5)
    From inequalities (3) and (5)
         x < -1.769713 或  x ＞ 0.769713    (6)
    From inequalities (4) and (6)
         x < -1.769713 或  x ＞ 0.769713    (7)

---

    The final solution set is :
         x < -1.769713 或  x ＞ 0.769713
