[ 1/1Inequality]
Assignment:Find the solution set of inequality e^(-x/4) ≤10^(-4)×√(πx) .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
e ^ ( -x / 4 ) ≤10 ^ ( -4 ) × √ ( π * x ) (1)
From the definition field of √
π * x ≥ 0 (2 )
From inequality(1):
x ≥ 13947503/500000
From inequality(2):
x ≥ 0
From inequalities (1) and (2)
x ≥ 13947503/500000 (3)
The final solution set is :
x ≥ 13947503/500000Your problem has not been solved here? Please take a look at the hot problems !
