Assignment:Find the solution set of inequality 1000000*(1+x)^30 >5615.31*(1-(x/12)^359)/(1-x/12) .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
1000000 * ( 1 + x ) ^ 30 >5615.31 * ( 1 - ( x / 12 ) ^ 359 ) / ( 1 - x / 12 ) (1)
From the definition field of divisor
1 - x / 12 ≠ 0 (2 )
From inequality(1):
-15.234239 < x < -1.837369 或 -0.159014 < x < 15.319174
From inequality(2):
x < 12 或 x > 12
From inequalities (1) and (2)
-15.234239 < x < -1.837369 或 -0.159014 < x < 12 或 12 < x < 15.319174 (3)
The final solution set is :
-15.234239 < x < -1.837369 或 -0.159014 < x < 12 或 12 < x < 15.319174 Your problem has not been solved here? Please take a look at the hot problems !
