u = (x^3 + x)
v = e^5x

The chain rule says that the derivative of u*v = u'v+uv'. The apostrophe is pronounced "prime" and means "derivative of". This is for any u and v by the way. So let's find u' and v'...

u' = 3x^2 + 1
v' = 5 * e^5x

Therefore the derivative of u*v is: (plugging in for u,u',v,v')

(3x^2 + 1)(e^5x) + (x^3+x)(5e^5x)

Which can be simplified as:

e^5x * (5x^3+3x^2+x+1)

There you go!
