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