[ 1/1Inequality]
    Assignment:Find the solution set of inequality ((10^(-6))+(10^(-21))*(x^2))*((2501*x+(10^8)) ) >= (5*(10^(-6))*x+500)/(0.18) .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( ( 10 ^ ( -6 ) ) + ( 10 ^ ( -21 ) ) * ( x ^ 2 ) ) * ( ( 2501 * x + ( 10 ^ 8 ) ) ) >= ( 5 * ( 10 ^ ( -6 ) ) * x + 500 ) / ( 0.18 )         (1)

---

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

---

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