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

    From inequality(1):
         -0.5 < x < 1/2
    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):
         -1/2 < x < 0 或  x > 0

    From inequalities (1) and (2)
         -0.5 < x < 1/2     (4)
    From inequalities (3) and (4)
         -1/2 < x < 0 或  0 < x < 1/2     (5)

    The final solution set is :

         -1/2 < x < 0 或  0 < x < 1/2
