[ 1/1Inequality]
Assignment:Find the solution set of inequality (1000-10n)/n^0.5 >1.65 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 1000 - 10 * n ) / n ^ 0.5 >1.65 (1)
From the definition field of divisor
x ≠ 0 (2 )
From inequality(1):
n < 98.363556
From inequality(2):
n < 0 或 n > 0
From inequalities (1) and (2)
n < 0 或 0 < n < 98.363556 (3)
The final solution set is :
n < 0 或 0 < n < 98.363556 Your problem has not been solved here? Please take a look at the hot problems !
