[ 1/1Inequality]
    Assignment:Find the solution set of inequality 0.9ln(x) ≥ln(2*x) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
        0.9 * ln ( x ) ≥ ln ( 2 * x )         (1)
        From the definition field of ln
         x > 0        (2 )
        From the definition field of ln
         2 * x > 0        (3 )

    From inequality(1):
         x ≤ 0.000977
    From inequality(2):
         x > 0
    From inequality(3):
         x > 0

    From inequalities (1) and (2)
         0 < x ≤ 0.000977     (4)
    From inequalities (3) and (4)
         0 < x ≤ 0.000977     (5)

    The final solution set is :

         0 < x ≤ 0.000977
