Although other posters have been trying to answer you question, I find
it so unclear that I don't know where to start.

Presumably g is in G and n is a postive integer (although, reading what
you write exactly, you seem to be saying that n is in G).

But what about x? Is that supposed to be an element of G,
or is it an integer too?
And what has order q? Is it G, or g^x ?
