[ 1/1Inequality]
    Assignment:Find the solution set of inequality (x^9+x^5-45)/(9+x^7) >(x^-5)+7 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( x ^ 9 + x ^ 5 - 45 ) / ( 9 + x ^ 7 ) > ( x ^ -5 ) + 7         (1)
        From the definition field of divisor
         9 + x ^ 7 ≠ 0        (2 )

---

    From inequality(1)：
         x < -2.589188 或  -1.602516 < x < -1.368738 或  -0.608084 < x < 0 或  x ＞ 2.642838
    From inequality(2)：
         x < -1.368738 或  x ＞ -1.368738

---

    From inequalities (1) and (2)
         x < -2.589188 或  -1.602516 < x < -1.368738 或  -0.608084 < x < 0 或  x ＞ 2.642838    (3)

---

    The final solution set is :
         x < -2.589188 或  -1.602516 < x < -1.368738 或  -0.608084 < x < 0 或  x ＞ 2.642838
