[ 1/1Inequality]
    Assignment:Find the solution set of inequality 1314520 >√（x^x^x^x^x^x^x^x^x） >5201314 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        1314520 > √ ( x ^ x ^ x ^ x ^ x ^ x ^ x ^ x ^ x )         (1)
         √ ( x ^ x ^ x ^ x ^ x ^ x ^ x ^ x ^ x ) >5201314         (2)
        From the definition field of √
         x ^ x ^ x ^ x ^ x ^ x ^ x ^ x ^ x ≥ 0        (3 )

---

    From inequality(1)：
         x < 1.653957
    From inequality(2)：
         x ＞ 1.669484
    From inequality(3)：
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!

---

    From inequalities (1) and (2)
        x ∈ Φ (Φ is empty)that is, the inequality will never be estatlished within the real number range!    (4)
    From inequalities (3) and (4)
        x ∈ Φ (Φ is empty)that is, the inequality will never be estatlished within the real number range!    (5)

---

    The final solution set is :
        x ∈ Φ (Φ is empty)that is, the inequality will never be estatlished within the real number range!
