Assignment:Find the solution set of inequality e^x >6*ln(x+3) .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality:
e ^ x >6 * ln ( x + 3 ) (1)
From the definition field of ln
x + 3 > 0 (2 )
From inequality(1):
x < -1.976642 或 x > 2.303618
From inequality(2):
x > -3
From inequalities (1) and (2)
-3 < x < -1.976642 或 x > 2.303618 (3)
The final solution set is :
-3 < x < -1.976642 或 x > 2.303618Your problem has not been solved here? Please take a look at the hot problems !
