Question

Hi I wasn't sure on how to start the problem. I'm not sure how to go about looking for the proof 

Find the mean value, the standard deviation and the skewness of the exponential distribution:
fx(x) = { ke
ke-k for 1>0
otherwise
where k is a positive constant. Also, prove for this distribution that the moment about the
origin of order n is given by: n!/k".
