Arithmetic magic

David Blaine asked the spectator to conceive two numbers. Then he asked to multiply two numbers, each of which greater than conceived by one, then to subtract one conceived number from the result, then to subtract the other, and then to subtract their product, and raise the result to the $n$-th power.

After that, David carefully looked into the face of the spectator and correctly told the result. Your task is to repeat the focus of David. Given value of $n$, guess the number obtained by the spectator.
