i have to find the z transform of 2^n + 3, so i broke it up into Z[2^n] + Z[3].. i know Z[2^n] is z/(z-2), but im not sure of the other... i'm thinking 0, but not sure

Probably too late to help but it looks to me from this table:

that the z-transform of 3 might be 3z/(z+1)?

If a variable does not appear in an equation, that variable has no effect; therefore that variable would always transform as zero. To prove that, add 0z to the equation. Does it change the equation? No, it's exactly equivalent.

3z/z-1
u(n) = 1
Z- transform for [u(n)] = z/z-1
3u(n)= 3*1
Z- transform for [ 3u(n) ] = 3* z/z-1
