[ 1/1Inequality]
Assignment:Find the solution set of inequality (2-0.5^(x-1))/(2-0.5^(x-2)) >2 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
( 2 - 0.5 ^ ( x - 1 ) ) / ( 2 - 0.5 ^ ( x - 2 ) ) >2 (1)
From the definition field of divisor
2 - 0.5 ^ ( x - 2 ) ≠ 0 (2 )
From inequality(1):
1 < x < 1.584962
From inequality(2):
x < 1 或 x > 1
From inequalities (1) and (2)
1 < x < 1.584962 (3)
The final solution set is :
1 < x < 1.584962 Your problem has not been solved here? Please take a look at the hot problems !
