[ 1/1Inequality]
    Assignment:Find the solution set of inequality (1/5)^(2*x+1)/(x*2+1) <1*10^-15 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 1 / 5 ) ^ ( 2 * x + 1 ) / ( x * 2 + 1 ) <1 * 10 ^ -15         (1)
        From the definition field of divisor
         x * 2 + 1 ≠ 0        (2 )

---

    From inequality(1)：
         x < -0.5 或  x ＞ 18611/2000
    From inequality(2)：
         x < -1/2 或  x ＞ -1/2

---

    From inequalities (1) and (2)
         x < -0.5 或  x ＞ 18611/2000    (3)

---

    The final solution set is :
         x < -0.5 或  x ＞ 18611/2000
