Question from chaptay, a student:

what is the difference between x(n^2) and x(n)^2

Hi Chaptay,

There is no difference between the two expressions you sent, they are both x times n2. I wonder however if you are asking for the difference between xn2 and (xn)2. If this is what you are asking ook at n = 3.

x32 = x9 and (x3)2 = x6.
