[ 1/1Inequality]
    Assignment:Find the solution set of inequality (1+x+0.65)*1.21^2*1.12^2*1.057 >(1+x)*1.21^3*1.12^3 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 1 + x + 0.65 ) * 1.21 ^ 2 * 1.12 ^ 2 * 1.057 > ( 1 + x ) * 1.21 ^ 3 * 1.12 ^ 3         (1)

---

    From inequality(1)：
         x < 1.303991

---

    The final solution set is :
         x < 1.303991
