 Id like to know how or where obtain a step by step transform. One example could be: 1/(1+3s)^nThank you in advance and excuse me for my ignorance

 In[3]:= LaplaceTransform[(1 + 3 t)^-n, t, s] Out[3]= 1/3 E^(s/3) ExpIntegralE[n, s/3] In[4]:= Integrate[(1 + 3 t)^-n Exp[-s t], {t, 0, \[Infinity]}] Out[4]= ConditionalExpression[1/3 E^(s/3) ExpIntegralE[n, s/3], Re[s] > 0 || (Re[s] >= 0 && Re[n] > 1)]

 Is this a solution step by step? It doesnt seem to me but I may be wrong. Id like to obtain the exact procedure to calculate this transform on paper.

 Quite possibly W|A simply does not support Show Steps for the Laplace transform.
