For the following exercises, the vectors u and v are given. Use determinant notation to find vector w orthogonal to vectors u and v.
Find vector (a − 2b) × c, where
\(\mathbf{a}=\left|\begin{array}{rrr}
\mathbf{i} & \mathbf{j} & \mathbf{k} \\
2 & -1 & 5 \\
0 & 1 & 8
\end{array}\right|, \quad \mathbf{b}=\left|\begin{array}{rrr}
\mathbf{i} & \mathbf{j} & \mathbf{k} \\
0 & 1 & 1 \\
2 & -1 & -2
\end{array}\right|\) and c = i + j + k.
