A question (please help)

The following is an example of a practice test I've taken but has really confused me.
You are creating a class A network with 8 subnets. What will the subnet mask be?
I've seen 2 different formulas.....
2^n-2
and
2^n
I don't actually use either of those methods for finding a subnet mask. Mine works just fine but the question did not specify usable subnets....
So my question is.... If I were to run across something like this on the test Would I assume usable or unusable subnets?

Thanks for the reply Darby! Every practice test I've taken so far is assuming usable. So I think you are right that I should assume usable on the real exam unless otherwise specified. I will be taking the exam sometime between now and the end of next week... Just waiting on my voucher code to come in. I'll let you all know how I do.
Once again thanks!

Good luck on the 2K Beast! Please let us know how you did when you finally make the attempt..
I usually hang out on 224.0.0.10 (FF02::A) and 224.0.0.5 (FF02::5) when I'm in a non-proprietary mood.
