    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        1314 > x ^ x         (1)
         x ^ x >520         (2)

---

    From inequality(1)：
         x < 4.663552
    From inequality(2)：
         x ＞ 4.292588

---

    From inequalities (1) and (2)
         4.292588 < x < 4.663552     (3)

---
