# Laplace transform

Hello I'm struggling to understand some basics here with the laplace transform..

I'm given the laplace transform of

2/(s + 4)^4

and I need to take the inverse of this to get back to y(t)
Looking at my tables the only transform similar to this is 1/(s + a)^2

I understand I can pull out the 2 and write it in the form 2[ 1/(s + 4)^4 ] but this is where i'm stuck can I do this..

2[ 1/ (s + 4)^2 * 1/(s + 4)^2 ] and then since the inverse of 1/(s + 4)^2 = te^-4t would i just multiply te^-4t * te^-4t ? is that allowed or what other route would should I take?
