Text Solution
Verified by ExpertsThe correct answer is:
2
(2)
Given,
Now 
So, the equation becomes
, ignoring negative sign as exponential function are positive,
Now 
which is quadratic equation in e 2x with upward parabola,
Now by A. M 
G. M we get, 
So, 
, hence it will cut at two distinct point,
Hence, there will be two solution.
