(29) answer should be C if x and y is not specified as integers..

Assume p=-1

Say x=2 and y=1/2, you will have p^(xy)=-1, while p^x=1

Still 29. Notice the difference between (p^x)^y and p^(xy).

Assuming the question is asking to determine the value of p^(xy).

p^x=1 doesnt necessarily lead to p^(xy)=1;

Try p=-1, x=2, and y=1/2,

you have p^x=1, but p^(xy)=-1.

If the question is asking about the value of (p^x)^y,

the answer you provided is correct.
