1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution i have answered the first part, explained why its a basis i think that i need to show that the N(T) = V alongside R(T) = W will give matrices that cannot be multiplied therefore T is the one that cant exist not sure though and i think for the final part i just multiply such matrix but i dont know what to multiply?! very confusing!
