[ 1/1Inequality]
    Assignment:Find the solution set of inequality log(0.2,2-x) ≥0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         log( 0.2 , 2 - x ) ≥0         (1)
        From the definition field of log
         0.2 > 0        (2 )
         2 - x > 0 also ≠ 1        (3 )

---

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

---

    From inequalities (1) and (2)
         x ≥ 1    (4)
    From inequalities (3) and (4)
         1 < x < 2     (5)

---

    The final solution set is :
         1 < x < 2
