[ 1/1Inequality]
    Assignment:Find the solution set of inequality 0     Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        0 < sqrt ( 2 ^ x - 1 )         (1)
         sqrt ( 2 ^ x - 1 ) <2         (2)
        From the definition field of √
         2 ^ x - 1 ≥ 0        (3 )

---

    From inequality(1)：
         x ＞ 0
    From inequality(2)：
         x < 2.321928
    From inequality(3)：
         x ≥ 0

---

    From inequalities (1) and (2)
         0 < x < 2.321928     (4)
    From inequalities (3) and (4)
         0 < x < 2.321928     (5)

---

    The final solution set is :
         0 < x < 2.321928
