[ 1/1Inequality]
    Assignment:Find the solution set of inequality (1+(1-(1-a)^8)*(46*a+12)/(2+5*a)) <9-8*(1-a)^8 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 1 + ( 1 - ( 1 - a ) ^ 8 ) * ( 46 * a + 12 ) / ( 2 + 5 * a ) ) <9 - 8 * ( 1 - a ) ^ 8         (1)
        From the definition field of divisor
         2 + 5 * x ≠ 0        (2 )

---

    From inequality(1)：
         a < -0.4 或  0 < a < 2/3 或  a ＞ 2
    From inequality(2)：
         a < -2/5 或  a ＞ -2/5

---

    From inequalities (1) and (2)
         a < -0.4 或  0 < a < 2/3 或  a ＞ 2    (3)

---

    The final solution set is :
         a < -0.4 或  0 < a < 2/3 或  a ＞ 2
