[ 1/1Inequality]
    Assignment:Find the solution set of inequality √(x-2021) ≤0 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         √ ( x - 2021 ) ≤0         (1)
        From the definition field of √
         x - 2021 ≥ 0        (2 )

---

    From inequality(1)：
         x ≤ 2021
    From inequality(2)：
         x ≥ 2021

---

    From inequalities (1) and (2)
         2021 ≤ x ≤ 2021    (3)

---

    The final solution set is :
         2021 ≤ x ≤ 2021
