[ 1/1Inequality]
    Assignment:Find the solution set of inequality 0 <2a-√4a*a-4 <2 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        0 <2 * a - √ 4 * a * a - 4         (1)
        2 * a - √ 4 * a * a - 4 <2         (2)

---

    From inequality(1)：
        The solution set is empty, that is, within the range of real numbers, the inequality will never be established!
    From inequality(2)：
         a ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!

---

    The final solution set is :
        The solution set is empty,that is, the inequality will never be estatlished within the real number range.
