[ 1/1Inequality]
    Assignment:Find the solution set of inequality 99.5 ≤√(3200^2+2000^2)/x <100.5 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        99.5 ≤ √ ( 3200 ^ 2 + 2000 ^ 2 ) / x         (1)
         √ ( 3200 ^ 2 + 2000 ^ 2 ) / x <100.5         (2)
        From the definition field of divisor
        x ≠ 0        (3 )

---

    From inequality(1)：
         0 ≤ x ≤ 37.925552
    From inequality(2)：
         x < 0 或  x ＞ 37.548184
    From inequality(3)：
         x < 0 或  x ＞ 0

---

    From inequalities (1) and (2)
         37.548184 < x ≤ 37.925552     (4)
    From inequalities (3) and (4)
         37.548184 < x ≤ 37.925552     (5)

---

    The final solution set is :
         37.548184 < x ≤ 37.925552
