[ 1/1Inequality]
Assignment:Find the solution set of inequality (1350*(((1+x)^7)-1)/(x*(1+x)))-9000 >0 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 1350 * ( ( ( 1 + x ) ^ 7 ) - 1 ) / ( x * ( 1 + x ) ) ) - 9000 >0 (1)
From the definition field of divisor
x * ( 1 + x ) ≠ 0 (2 )
From inequality(1):
-1 < x < -0.816229 或 x > -0.024711
From inequality(2):
x < -1 或 -1 < x < 0 或 x > 0
From inequalities (1) and (2)
-1 < x < -0.816229 或 -0.024711 < x < 0 或 x > 0 (3)
The final solution set is :
-1 < x < -0.816229 或 -0.024711 < x < 0 或 x > 0Your problem has not been solved here? Please take a look at the hot problems !
