[ 1/1Inequality]
    Assignment:Find the solution set of inequality (8*(2/3)^k)/(45-16*(2/3)^k) <0.001 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 8 * ( 2 / 3 ) ^ k ) / ( 45 - 16 * ( 2 / 3 ) ^ k ) <0.001         (1)
        From the definition field of divisor
         45 - 16 * ( 2 / 3 ) ^ x ≠ 0        (2 )

---

    From inequality(1)：
         k < -2.55034 或  k ＞ √163371789/1000
    From inequality(2)：
         k < -2.55034 或  k ＞ -2.55034

---

    From inequalities (1) and (2)
         k < -2.55034 或  k ＞ √163371789/1000    (3)

---

    The final solution set is :
         k < -2.55034 或  k ＞ √163371789/1000
