Consider the vectors \(\mathbf{u}\) and \(\mathbf{v}\) with the given inner product.
\(\mathbf{u} = (1, 1, 1)\),
\(\mathbf{v} = (3, -4, 5)\), \((\mathbf{u}, \mathbf{v}) = u_1v_1 + 2u_2v_2 + u_3v_3\
Find the lengths of \(\mathbf{u}\) and \(\mathbf{v}\) and their inner product.
\(\|\mathbf{u}\|\) =
\(\|\mathbf{v}\|\) =
\((\mathbf{u}, \mathbf{v})\) =
