Inverse Laplace for (e)^-5t*(t)^4

    1. The problem statement, all variables and given/known data

    Find:

    Inverse Laplace for x(t)= (e)^-5t*(t)^4 using laplace table and laplace properties.

    2. Relevant equations



    3. The attempt at a solution

    Well, I have been working on this problem for a few days now and cannot seem to figure it out. The two functions are not seperate terms being added together so I cannot simply say

    L^-1{(e)^-5t} + L^-1{(t)^4} which I originally tried. This would result in

    1/s+5 + 24/s^5 which would be easy but since the two functions are being multiplied it is throwing me off and I cannot find an answer through the tables.

    I found a better table, this post can be deleted
