    Assignment:Find the solution set of inequality 0.81x*x*x*x+62x*x ≤1900 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        0.81 * x * x * x * x + 62 * x * x ≤1900         (1)

---

    From inequality(1)：
         -4.843221 ≤ x ≤ 4.843221

---

    The final solution set is :
         -4.843221 ≤ x ≤ 4.843221
