It is not "who" but "how"...!נו באמת
Anyway: how many elements in V can be the first element in the basis? (all but the zero vector): how many elements can be the second element in a basis? (all but the scalar multiples of the first one, and there are q multiples like these), etc.
Try now to do the second part by yourself.

Shalom! I am mitbaesh beatzmi...
Can you please write the whole answer for the question.
1. q^n-1 ?
2.?
p.s:
What is MHF expert mean?

choices for the second vector (all the available vectors minus those that are a scalar multiple of the first one), then there are
choices for the third one (all the possible vectors minus all the scalar multiples of the first two), etc.
All in, there are...try to end the argument by yourself now.
