Hi,

I was doing some GRE practice tests and came across this question:

for all number n, [tex]n^*[/tex]=32-n (apparently where the asterisk is an exponent)

They then give me two values, which are [tex](n^*)^*[/tex] and n, and I am to say whether choice 1 is a greater value than choice 2, choice 2 is a greater value than choice 1, the two values are equal, or there is not enough info to determine. The answer key says they are equal. This means given the above equation, [tex](n^*)^*[/tex] = n

I can't see how this is true... Anyone care to explain? Thanks
