I am not sure. I am reading a book of Linear Algebra. this problem is in that book. if n is odd ,and ,I have proved . when n is even ,i have no idea.
If ,I am not sure whether the conclusion was right?

thanks very much.
well, this is not very helpful! post the question exactly as you've seen it. do not add anything to it! then i'll help you to solve it.
assuming that is the identity matrix (this is an unusual notation for the identity matrix and you should've mentioned what it means!) this still can't be the question because it's false!
