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

    From inequality(1):
         -0.861345 < n < 1.239628 或  n > 16
    From inequality(2):
         n ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(3):
         n < -1 或  -1 < n < 0 或  0 < n < 1 或  n > 1

    From inequalities (1) and (2)
         -0.861345 < n < 1.239628 或  n > 16    (4)
    From inequalities (3) and (4)
         -0.861345 < n < 0 或  0 < n < 1 或  1 < n < 1.239628 或  n > 16    (5)

    The final solution set is :

         -0.861345 < n < 0 或  0 < n < 1 或  1 < n < 1.239628 或  n > 16
