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

    From inequality(1):
         X > 2/3
    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 < 1 或  X > 1

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

    The final solution set is :

         2/3 < X < 1 或  X > 1
