If you put it in parentheses, (mm Hg)^2, it's the same as mm^2 Hg, and correct. However, just mm Hg^2 would be wrong, and confusing, because you'd be squaring mercury, which makes no sense.

People will understand it either way, but if you are being pedantic, you're actually squaring the unit of measure (the mm). So it should read mm^2 Hg.
Good luck, work hard, and stay away from drugs.

Do neither. Use the SI metric unit of pressure, the Pascal. It is a standard unit and leaves no room for confusion or ambiguity.
