Assignment:Find the solution set of inequality ln(x)+sqrt(x) ≥0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
ln ( x ) + sqrt ( x ) ≥0 (1)
From the definition field of ln
x > 0 (2 )
From the definition field of √
x ≥ 0 (3 )
From inequality(1):
x ≥ 0.494866
From inequality(2):
x > 0
From inequality(3):
x ≥ 0
From inequalities (1) and (2)
x ≥ 0.494866 (4)
From inequalities (3) and (4)
x ≥ 0.494866 (5)
The final solution set is :
x ≥ 0.494866Your problem has not been solved here? Please take a look at the hot problems !
