    Assignment:Find the solution set of inequality （1280-i+3)/2^(i+2) >= 5 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 1280 - i + 3 ) / 2 ^ ( i + 2 ) >= 5         (1)

---

    From inequality(1)：
         i ≤ 5.996619

---

    The final solution set is :
         i ≤ 5.996619
