Are you assuming s is an integer? Otherwise you should probably use the gamma function. Anywho, can you think of anyway to check which of those answers is correct? Possibly using the fact that a gamma density integrates to 1?

My question is for the lambda part in the denominator, is it lambda^(s) or lambda^(s-1) ?

The main part of the post is saying you should be able to deduce which it is by using the fact that a gamma density integrates to 1. Which of the two do you think it is and why?
