I need to clear my mind in order to solve some excersices: I need to proof that $\mathbb{C}^{n_1} \oplus \mathbb{C}^{n_2} \cong \mathbb{C}^{n_1+n_2}$ where $\mathbb{C}^{n_1}$ and $\mathbb{C}^{n_1}$ are Hilbert spaces, but I'm not so clear about what I need to prove. Could you please help me by giving me some tips?
