[ 1/1Inequality]
    Assignment:Find the solution set of inequality x^2*e(5^2/(5^2-x^2)) <= 2 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x ^ 2 * e ( 5 ^ 2 / ( 5 ^ 2 - x ^ 2 ) ) <= 2         (1)
        From the definition field of divisor
         5 ^ 2 - x ^ 2 ≠ 0        (2 )

---

    From inequality(1)：
         -5.817107 ≤ x ≤ -5 或  -0.845239 ≤ x ≤ 0.845239 或  5 ≤ x ≤ 5.817107
    From inequality(2)：
         x < -5 或  -5 < x < 5 或  x ＞ 5

---

    From inequalities (1) and (2)
         -5.817107 ≤ x < -5 或  -0.845239 ≤ x ≤ 0.845239 或  5 < x ≤ 5.817107     (3)

---

    The final solution set is :
         -5.817107 ≤ x < -5 或  -0.845239 ≤ x ≤ 0.845239 或  5 < x ≤ 5.817107
