Assignment:Find the solution set of inequality 0.15x/(ln(x+5474.3)-3.8) <1430.1 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
0.15 * x / ( ln ( x + 5474.3 ) - 3.8 ) <1430.1 (1)
From the definition field of ln
x + 5474.3 > 0 (2 )
From the definition field of divisor
ln ( x + 5474.3 ) - 3.8 ≠ 0 (3 )
From inequality(1):
x < -5449.059235 或 x > -5429.598816
From inequality(2):
x > -54743/10
From inequality(3):
x < -5429.598816 或 x > -5429.598816
From inequalities (1) and (2)
-54743/10 < x < -5449.059235 或 x > -5429.598816 (4)
From inequalities (3) and (4)
-54743/10 < x < -5449.059235 或 x > -5429.598816 (5)
The final solution set is :
-54743/10 < x < -5449.059235 或 x > -5429.598816Your problem has not been solved here? Please take a look at the hot problems !
