Let u=123,v=456\mathbf u = \begin{bmatrix} 1 \\ 2 \\3 \end{bmatrix}, \mathbf v = \begin{bmatrix} 4 \\ 5\\6\end{bmatrix} , and b=210 \mathbf b = \begin{bmatrix} 2 \\ 1\\0\end{bmatrix} a. (3 points) Write any three vectors in Span {u,v} \{\mathbf u, \mathbf v \} b. (7 points) Determine if b\mathbf b lies in Span {u,v} \{\mathbf u, \mathbf v \}
