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

---

    From inequality(1)：
         x < -6
    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 < -6    (4)
    From inequalities (3) and (4)
         x < -6    (5)

---

    The final solution set is :
         x < -6
