[ 1/1Inequality]
    Assignment:Find the solution set of inequality 140 ≤(1+(0.5*0.5)/(1.13*x*1.13*x)*2)*120 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        140 ≤ ( 1 + ( 0.5 * 0.5 ) / ( 1.13 * x * 1.13 * x ) * 2 ) * 120         (1)
        From the definition field of divisor
         1.13 * x * 1.13 * x ≠ 0        (2 )

---

    From inequality(1)：
         -1.532788 ≤ x ≤ 1.532788
    From inequality(2)：
         x < 0 或  x ＞ 0

---

    From inequalities (1) and (2)
         -1.532788 ≤ x < 0 或  0 < x ≤ 1.532788     (3)

---

    The final solution set is :
         -1.532788 ≤ x < 0 或  0 < x ≤ 1.532788
