[ 1/1Inequality]
Assignment:Find the solution set of inequality 570*1000/(935641+x+1000)*5 <1000*0.003 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
570 * 1000 / ( 935641 + x + 1000 ) * 5 <1000 * 0.003 (1)
From the definition field of divisor
935641 + x + 1000 ≠ 0 (2 )
From inequality(1):
The solution set is empty, that is, within the range of real numbers, the inequality will never be established!
From inequality(2):
x ∈ R (R为全体实数),即在实数范围内,不等式恒成立!
The final solution set is :
The solution set is empty,that is, the inequality will never be estatlished within the real number range.
