8 The vectors \(\mathbf { a } , \mathbf { b }\), and \(\mathbf { c }\) are such that \(\mathbf { a } \times \mathbf { b } = \left[ \begin{array} { l } 2
1
0 \end{array} \right]\) and \(\mathbf { a } \times \mathbf { c } = \left[ \begin{array} { l } 0
0
3 \end{array} \right]\)
Work out \(( \mathbf { a } - \mathbf { 4 } \mathbf { b } + \mathbf { 3 c } ) \times ( \mathbf { 2 a } )\)
