[ 1/1Inequality]
    Assignment:Find the solution set of inequality 15*(n-1)-5sqrt(3*(n-1)) >-20 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        15 * ( n - 1 ) - 5 * sqrt ( 3 * ( n - 1 ) ) > -20         (1)
        From the definition field of √
         3 * ( x - 1 ) ≥ 0        (2 )

---

    From inequality(1)：
         n ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(2)：
         n ≥ 1

---

    From inequalities (1) and (2)
         n ≥ 1    (3)

---

    The final solution set is :
         n ≥ 1
