Let V = R' and define vector addition as (x, y, z)+(x', y', z')= (x+x',y+y',z+z') (standard addition) and scalar multiplication as k(x, y, z) = (kx,ky, 2z) (not the standard scalar multiplication). Determine if V is a vector space.

Question
Let \( V = \mathbb{R}^3 \) and define vector addition as \((x, y, z) + (x', y', z') = (x + x', y + y', z + z')\) (standard addition) and scalar multiplication as \(k(x, y, z) = (kx, ky, 2z)\) (not the standard scalar multiplication). Determine if \( V \) is a vector space.
