How can I show whether the following vectors form a free basis of Z3?
(1,2,2), (-1,0,2), (2,-1,4)
Is a free basis the same as a normal basis and does the method for determining linear independence change when the vector space is Z3 rather than R3?
I have injection f:A→B and I want to get bijection. Can I just resting codomain to f(A)? I know that every function i...
