[ 1/1Inequality]
    Assignment:Find the solution set of inequality sqrt（9+m）（18+m） >162 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         sqrt ( 9 + m ) * ( 18 + m ) >162         (1)
        From the definition field of √
         9 + x ≥ 0        (2 )

---

    From inequality(1)：
         m ＞ 15.040349
    From inequality(2)：
         m ≥ -9

---

    From inequalities (1) and (2)
         m ＞ 15.040349    (3)

---

    The final solution set is :
         m ＞ 15.040349
