No, certainly not. There's no absolute answer, see here for a good discussion.

I think it means x degrees rather than x to the power of 0.

I can't see the question properly, what is x tending to?

Neither, as far as I can tell. Your answer is certainly wrong - if you take the limit as x->a, then you can't have an x appearing in your answer.
5. As a side point, is definitely equal to 1*, regardless of what "0^0" equals. There's a good reason you take limits rather than just evaluating directly. But yes, tommm is right, it's meant to be x degrees. Can you do this question now?

(* though notice that , which is why we call 0^0 indeterminate)
