    Assignment:Find the solution set of inequality 0     Question type: Inequality
    Solution:
    The inequality can be reduced to 5 inequalities：
        0 < x * x * x * x         (1)
         x * x * x * x < x * x * x         (2)
         x * x * x < x * x         (3)
         x * x < x         (4)
         x <1         (5)

---

    From inequality(1)：
         x < 0 或  x ＞ 0
    From inequality(2)：
         0 < x < 1
    From inequality(3)：
         x < 0 或  0 < x < 1
    From inequality(4)：
         0 < x < 1
    From inequality(5)：
         x < 1

---

    From inequalities (1) and (2)
         0 < x < 0 或  0 < x < 1     (6)
    From inequalities (3) and (6)
         0 < x < 0 或  x ＞ 0 或  0 < x < 1     (7)
    From inequalities (4) and (7)
         0 < x < 0 或  0 < x < 1     (8)
    From inequalities (5) and (8)
         0 < x < 0 或  0 < x < 1     (9)

---

    The final solution set is :
         0 < x < 0 或  0 < x < 1
