[ 1/1Inequality]
Assignment:Find the solution set of inequality 8(ln80+10ln2+10+10lnx-10ln10) <= 0.01x .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
8 * ( ln 80 + 10 * ln 2 + 10 + 10 * ln x - 10 * ln 10 ) <= 0.01 * x (1)
From the definition field of ln
x > 0 (2 )
From inequality(1):
x ≤ 1.186946
From inequality(2):
x > 0
From inequalities (1) and (2)
0 < x ≤ 1.186946 (3)
The final solution set is :
0 < x ≤ 1.186946 Your problem has not been solved here? Please take a look at the hot problems !
