[ 1/1Inequality]
    Assignment:Find the solution set of inequality √(-ex) <10000000 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         √ ( -e x ) <10000000         (1)
        From the definition field of √
         -e x ≥ 0        (2 )

---

    From inequality(1)：
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(2)：
         x ≤ -750.796049 或  -750.796049 ≤ x ≤ -750.236914 或  -750.236914 ≤ x ≤ -67471/90 或  -67471/90 ≤ x ≤ -749.118642 或  -749.118642 ≤ x ≤ -748.559506 或  -748.559506 ≤ x ≤ -74800037/100000 或  -74800037/100000 ≤ x ≤ -747.441235 或  -747.441235 ≤ x ≤ -746.882099 或  -746.882099 ≤ x ≤ -746.322963 或  -746.322963 ≤ x ≤ -745.763827 或  x ≥ -745.763827

    From inequalities (1) and (2)
         x ≤ -750.796049 或  -750.796049 ≤ x ≤ -750.236914 或  -750.236914 ≤ x ≤ -67471/90 或  -67471/90 ≤ x ≤ -749.118642 或  -749.118642 ≤ x ≤ -748.559506 或  -748.559506 ≤ x ≤ -74800037/100000 或  -74800037/100000 ≤ x ≤ -747.441235 或  -747.441235 ≤ x ≤ -746.882099 或  -746.882099 ≤ x ≤ -746.322963 或  -746.322963 ≤ x ≤ -745.763827 或  x ≥ -745.763827    (3)

    The final solution set is :
         x ≤ -750.796049 或  -750.796049 ≤ x ≤ -750.236914 或  -750.236914 ≤ x ≤ -67471/90 或  -67471/90 ≤ x ≤ -749.118642 或  -749.118642 ≤ x ≤ -748.559506 或  -748.559506 ≤ x ≤ -74800037/100000 或  -74800037/100000 ≤ x ≤ -747.441235 或  -747.441235 ≤ x ≤ -746.882099 或  -746.882099 ≤ x ≤ -746.322963 或  -746.322963 ≤ x ≤ -745.763827 或  x ≥ -745.763827
