Expert Solution
Step 1

From chain rule 

If g(x) is a differentiable function, then the derivative of eg(x) is g'(x)*eg(x) .

Let y = eg(x) , differentiating y with respect to x

  dy/dx = d/dx[eg(x)]

Let g(x) = t , y becomes y=et

dy/dx can be written as 

dy/dx = (dy/dt)*(dt/dx)

dy/dx = d/dt(y)*d/dx(t)

dy/dx = d/dt(e)*d/dx[g(x)]

dy/dx = e*g'(x)   , putting  the value of t

dy/dx = eg(x)*g'(x)

dy/dx = g'(x)*eg(x)

Using formula d/dx(e) = e
