[ 1/1Inequality]
    Assignment:Find the solution set of inequality 0.25x*√(100-x^2) >0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        0.25 * x * √ ( 100 - x ^ 2 ) >0         (1)
        From the definition field of √
         100 - x ^ 2 ≥ 0        (2 )

---

    From inequality(1)：
         x < -10 或  x ＞ 0
    From inequality(2)：
         -10 ≤ x ≤ 10

---

    From inequalities (1) and (2)
         0 < x ≤ 10     (3)

---

    The final solution set is :
         0 < x ≤ 10
