[ 1/1Inequality]
    Assignment:Find the solution set of inequality ln(1+1/x^1000)-(1+x^1000)^(1/1000)+x >= 0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality:
         ln ( 1 + 1 / x ^ 1000 ) - ( 1 + x ^ 1000 ) ^ ( 1 / 1000 ) + x >= 0         (1)
        From the definition field of divisor
        x ≠ 0        (2 )
        From the definition field of ln
         1 + 1 / x ^ 1000 > 0        (3 )

    From inequality(1):
         x ≤ 1049259/1000000 或  1049259/1000000 ≤ x ≤ 1049259/1000000 或  1049259/1000000 ≤ x ≤ 70571/62500 或  70571/62500 ≤ x ≤ 302253/250000 或  302253/250000 ≤ x ≤ 58/45 或  58/45 ≤ x ≤ 273753/200000 或  273753/200000 ≤ x ≤ 724321/500000 或  724321/500000 ≤ x ≤ 1528519/1000000 或  1528519/1000000 ≤ x ≤ 321679/200000 或  321679/200000 ≤ x ≤ 105517/62500 或  x ≥ 105517/62500
    From inequality(2):
         x < 0 或  x > 0
    From inequality(3):
         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 < 0 或  0 < x ≤ 1049259/1000000 或  1049259/1000000 ≤ x ≤ 1049259/1000000 或  1049259/1000000 ≤ x ≤ 70571/62500 或  70571/62500 ≤ x ≤ 302253/250000 或  302253/250000 ≤ x ≤ 58/45 或  58/45 ≤ x ≤ 273753/200000 或  273753/200000 ≤ x ≤ 724321/500000 或  724321/500000 ≤ x ≤ 1528519/1000000 或  1528519/1000000 ≤ x ≤ 321679/200000 或  321679/200000 ≤ x ≤ 105517/62500 或  x ≥ 105517/62500    (4)
    From inequalities (3) and (4)
         x < 0 或  0 < x ≤ 1049259/1000000 或  1049259/1000000 ≤ x ≤ 1049259/1000000 或  1049259/1000000 ≤ x ≤ 70571/62500 或  70571/62500 ≤ x ≤ 302253/250000 或  302253/250000 ≤ x ≤ 58/45 或  58/45 ≤ x ≤ 273753/200000 或  273753/200000 ≤ x ≤ 724321/500000 或  724321/500000 ≤ x ≤ 1528519/1000000 或  1528519/1000000 ≤ x ≤ 321679/200000 或  321679/200000 ≤ x ≤ 105517/62500 或  x ≥ 105517/62500    (5)

    The final solution set is :

         x < 0 或  0 < x ≤ 1049259/1000000 或  1049259/1000000 ≤ x ≤ 1049259/1000000 或  1049259/1000000 ≤ x ≤ 70571/62500 或  70571/62500 ≤ x ≤ 302253/250000 或  302253/250000 ≤ x ≤ 58/45 或  58/45 ≤ x ≤ 273753/200000 或  273753/200000 ≤ x ≤ 724321/500000 或  724321/500000 ≤ x ≤ 1528519/1000000 或  1528519/1000000 ≤ x ≤ 321679/200000 或  321679/200000 ≤ x ≤ 105517/62500 或  x ≥ 105517/62500
