[ 1/1Inequality]
    Assignment:Find the solution set of inequality (0.1*0.1*q*q)/(1+sqrt(1+0.1*0.1*q*q))^2 >0.9 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 0.1 * 0.1 * q * q ) / ( 1 + sqrt ( 1 + 0.1 * 0.1 * q * q ) ) ^ 2 >0.9         (1)
        From the definition field of √
         1 + 0.1 * 0.1 * x * x ≥ 0        (2 )
        From the definition field of divisor
         1 + sqrt ( 1 + 0.1 * 0.1 * x * x ) ≠ 0        (3 )

---

    From inequality(1)：
         q < -√36000 或  q ＞ √36000
    From inequality(2)：
         q ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(3)：
         q ∈ R （R为全体实数），即在实数范围内，不等式恒成立！

---

    From inequalities (1) and (2)
         q < -√36000 或  q ＞ √36000    (4)
    From inequalities (3) and (4)
         q < -√36000 或  q ＞ √36000    (5)

---

    The final solution set is :
         q < -√36000 或  q ＞ √36000
