[ 1/1Inequality]
    Assignment:Find the solution set of inequality -2(1+x)^1/2+(-8x^1/2lnx) >= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        -2 * ( 1 + x ) ^ 1 / 2 + ( -8 * x ^ 1 / 2 * ln x ) >= 0         (1)
        From the definition field of ln
        x > 0        (2 )

---

    From inequality(1)：
         0.154641 ≤ x ≤ 0.442849
    From inequality(2)：
         x ＞ 0

---

    From inequalities (1) and (2)
         0.154641 ≤ x ≤ 0.442849    (3)

---

    The final solution set is :
         0.154641 ≤ x ≤ 0.442849
