Determine the column of the matrix A are linearly independent, where A = beginbmatrix 0 & 1 & 4 1 & 2 & -1 5 & 8 & 0 endbmatrix

Determine the column of the matrix $A$ are linearly independent, where $A = \begin{bmatrix} 0 & 1 & 4 \ 1 & 2 & -1 \ 5 & 8 & 0 \end{bmatrix}$ [5]

$$A = \begin{bmatrix} 0 & 1 & 4 \ 1 & 2 & -1 \ 5 & 8 & 0 \end{bmatrix}$$ Task: determine whether the columns of $A$ are linearly independent. The columns are linearly independent iff $A\mathbf{x}=\mathbf{0}$ has only the trivial solution. A quick check is the determinant: if $\det A \neq 0$, co...
