Use the logarithmic differentiation to differentiate the function
y= (x+2)^2/(e^x*sqrt(x^2+16))
----
y+=+%28x%2B2%29%5E2%2Ae%5E%28-x%29%2A%28x%5E2%2B16%29%5E%28-0.5%29
Use the product rule:
d/dx(u*v*w) = (du/dx)*v*w + (dv/dx)*u*w + (dw/dx)*u*v
du/dx = 2(x+2)
dv/dx = -e%5E%28-x%29
dw/dx = %28-1%2F2%29%2A%28x%5E2%2B16%29%5E%28-1.5%29%2A2x+=+-x%2A%28x%5E2%2B16%29%5E%28-1.5%29

The rest is just bookkeeping.
