Assignment:Find the solution set of inequality x ≥((4.732/(0.000518635×x^0.25))^0.5)-22×x^0.15 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
x ≥ ( ( 4.732 / ( 0.000518635 × x ^ 0.25 ) ) ^ 0.5 ) - 22 × x ^ 0.15 (1)
From the definition field of divisor
0.000518635 × x ^ 0.25 ≠ 0 (2 )
From inequality(1):
x ≥ 27.132474
From inequality(2):
x ∈ R (R为全体实数),即在实数范围内,不等式恒成立!
From inequalities (1) and (2)
x ≥ 27.132474 (3)
The final solution set is :
