[ 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 the definition field of √
         4 * x * x - 4 ≥ 0        (3 )

---

    From inequality(1)：
         a ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(2)：
         a ＞ 1
    From inequality(3)：
         a ≤ -1 或  a ≥ 1

---

    From inequalities (1) and (2)
         a ＞ 1    (4)
    From inequalities (3) and (4)
         a ＞ 1    (5)

---

    The final solution set is :
         a ＞ 1
