[ 1/1Inequality]
    Assignment:Find the solution set of inequality 1+16*1000000*r*r ≤0.081*(1+16000000*r*r)*(1+16000000*r*r) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        1 + 16 * 1000000 * r * r ≤0.081 * ( 1 + 16000000 * r * r ) * ( 1 + 16000000 * r * r )         (1)

---

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

---

    The final solution set is :
         r ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
