    Assignment:Find the solution set of inequality 10＾12+16*1000000*r*r ≤0.81*(100000+16*r*r)*(100000+16*r*r) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        10 ^ 12 + 16 * 1000000 * r * r ≤0.81 * ( 100000 + 16 * r * r ) * ( 100000 + 16 * r * r )         (1)

---

    From inequality(1)：
         r ≤ -329.660821 或  r ≥ 329.660821

---

    The final solution set is :
         r ≤ -329.660821 或  r ≥ 329.660821
