[ 1/1Inequality]
    Assignment:Find the solution set of inequality log(x,0.5) <1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         log( x , 0.5 ) <1         (1)
        From the definition field of log
         x > 0        (2 )
         0.5 > 0 also ≠ 1        (3 )

    From inequality(1):
         x < 1/2 或  x > 1
    From inequality(2):
         x > 0
    From inequality(3):
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!

    From inequalities (1) and (2)
         0 < x < 1/2 或  x > 1    (4)
    From inequalities (3) and (4)
         0 < x < 1/2 或  x > 1    (5)

    The final solution set is :

         0 < x < 1/2 或  x > 1
