    Assignment:Find the solution set of inequality k^4-2.5*k^2+0.5 >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         k ^ 4 - 2.5 * k ^ 2 + 0.5 >0         (1)

---

    From inequality(1)：
         k < -1.510224 或  -0.468213 < k < 0.468213 或  k ＞ 1.510224

---

    The final solution set is :
         k < -1.510224 或  -0.468213 < k < 0.468213 或  k ＞ 1.510224
