Prove that each of the following sets, with the indicated operation, is an abelian group. Instructions Proceed as in Chapter 2, Exercise B. x * y = x +y + k (k a fixed constant), on the set R of the real numbers. x * y = on the set {x elementof r: X notequalto 0}. x * y = x +y +xy, on the set {.x element of r: x notequalto to -1}. x * y = the set {x element of r: -1 Comments
