Assignment:Find the solution set of inequality 0 <50(2^2-n^3)^2
Question type: Inequality
Solution:
The inequality can be reduced to 2 inequalities:
0 <50 * ( 2 ^ 2 - n ^ 3 ) ^ 2 (1)
50 * ( 2 ^ 2 - n ^ 3 ) ^ 2 < n (2)
From inequality(1):
n < 1587401/1000000 或 n > 1587401/1000000
From inequality(2):
1.563654 < n < 1.610798
From inequalities (1) and (2)
1.563654 < n < 1587401/1000000 或 1587401/1000000 < n < 1.610798 (3)
The final solution set is :
1.563654 < n < 1587401/1000000 或 1587401/1000000 < n < 1.610798 Your problem has not been solved here? Please take a look at the hot problems !
