This is because surface can be treated as a normal vector by area. If you bound a surface by a loop, you can freely vary the surface, because the implication of $\int x^0 \;dq=0 $ is that the volume does not depend on the position of the observer's coordinate.
Webis called the kth moment of X. The “moment generating function” gives us a nice way of collecting to-gether all the moments of a random varaible X into a single power series (i.e. Maclaurin series) in the variable t. It is defined to be MX(t) := E(eXt) = E X∞ k=0 Xkt k!!. Thinking here of the t as a constant, at least from the ...
