[ 1/1Inequality]
    Assignment:Find the solution set of inequality 2x >x <4 >x^x <56x^-1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 4 inequalities：
        2 * x > x         (1)
         x <4         (2)
        4 > x ^ x         (3)
         x ^ x <56 * x ^ -1         (4)

---

    From inequality(1)：
         x ＞ 0
    From inequality(2)：
         x < 4
    From inequality(3)：
         x < 2
    From inequality(4)：
         x < 2.847153

---

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

---

    The final solution set is :
         0 < x < 2
