[ 1/1Inequality]
Assignment:Find the solution set of inequality (1-1/4^x)[2x(x+1)(2x+1)-3x]/18 >2sqrt(3) .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 1 - 1 / 4 ^ x ) * ( 2 * x * ( x + 1 ) * ( 2 * x + 1 ) - 3 * x ) / 18 >2 * sqrt ( 3 ) (1)
From inequality(1):
x < -1.934917 或 x > 2.154106
The final solution set is :
x < -1.934917 或 x > 2.154106Your problem has not been solved here? Please take a look at the hot problems !
