Then use the fact that two finite dimensional vector spaces over the same field are isomorphic if and only if they have the same dimension. In fact you can even find out basis of these two spaces, it's not that difficult. Frank Lu Frank Lu 5, 10 10 silver badges 28 28 bronze badges. Sign up or log in Sign up using Google.
