- Let R be the set of all infinite sequences of real numbers, with the operations u+v=(u1,u2,u3,......)+(v1,v2,v3,......)=(u1+v1,u2+v2,u3+v3,.....) and cu=c(u1,u2,u3,......)=(cu1,cu2,cu3,......). Determine whether R is a vector space. If it is, verify each vector space axiom; if it is not, state all vector space axioms that fail.arrow_forwardProve that the equalities in Exercises 111 hold for all x,y,zandw in Z. Assume only the basic postulates for Z and those properties proved in this section. Subtraction is defined by xy=x+(y). x0=0arrow_forward
