[ 1/1Inequality]
Assignment:Find the solution set of inequality n >= (log(2,n))^2 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
n >= ( log( 2 , n ) ) ^ 2 (1)
From the definition field of log
2 > 0 (2 )
x > 0 并且 ≠ 1 (3 )
From inequality(1):
0.587775 ≤ n ≤ 4 或 n ≥ 16
From inequality(2):
n ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
From inequality(3):
0 < n < 1 或 n > 1
From inequalities (1) and (2)
0.587775 ≤ n ≤ 4 或 n ≥ 16 (4)
From inequalities (3) and (4)
0.587775 ≤ n < 1 或 1 < n ≤ 4 或 n ≥ 16 (5)
The final solution set is :
0.587775 ≤ n < 1 或 1 < n ≤ 4 或 n ≥ 16Your problem has not been solved here? Please take a look at the hot problems !
