[ 1/1Inequality]
    Assignment:Find the solution set of inequality 0 <(10-x)÷(√((x-6)∧2+4)×√((8-3x÷2)∧2+1)) ≤1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities:
        0 < ( 10 - x ) ÷ ( √ ( ( x - 6 ) ^ 2 + 4 ) × √ ( ( 8 - 3 * x ÷ 2 ) ^ 2 + 1 ) )         (1)
         ( 10 - x ) ÷ ( √ ( ( x - 6 ) ^ 2 + 4 ) × √ ( ( 8 - 3 * x ÷ 2 ) ^ 2 + 1 ) ) ≤1         (2)
        From the definition field of √
         ( x - 6 ) ^ 2 + 4 ≥ 0        (3 )
        From the definition field of √
         ( 8 - 3 * x ÷ 2 ) ^ 2 + 1 ≥ 0        (4 )

    From inequality(1):
         x < 10
    From inequality(2):
         x ≤ 4.076065 或  x ≥ 6.336305
    From inequality(3):
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(4):
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!

    From inequalities (1) and (2)
         x ≤ 4.076065 或  6.336305 ≤ x < 10    (5)
    From inequalities (3) and (5)
         x ≤ 4.076065 或  6.336305 ≤ x < 10    (6)
    From inequalities (4) and (6)
         x ≤ 4.076065 或  6.336305 ≤ x < 10    (7)

    The final solution set is :

         x ≤ 4.076065 或  6.336305 ≤ x < 10
