    Assignment:Find the solution set of inequality 25π/（2×（5-4×x）×（5-4×x）×（1+24×x）） <1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        25 * π / ( 2 × ( 5 - 4 × x ) × ( 5 - 4 × x ) × ( 1 + 24 × x ) ) <1         (1)
        From the definition field of divisor
         2 × ( 5 - 4 × x ) × ( 5 - 4 × x ) × ( 1 + 24 × x ) ≠ 0        (2 )

---

    From inequality(1)：
         x < -0.041667 或  0.026668 < x < 0.924692 或  x ＞ 1.506974
    From inequality(2)：
         x < -0.041667 或  -0.041667 < x < 5/4 或  x ＞ 5/4

---

    From inequalities (1) and (2)
         x < -0.041667 或  0.026668 < x < 0.924692 或  x ＞ 1.506974    (3)

---

    The final solution set is :
         x < -0.041667 或  0.026668 < x < 0.924692 或  x ＞ 1.506974
