(A) To find the determinant of matrix $A$,we expand along the first row:$\det(A) = \begin{vmatrix} 1 & 0 & 1 \ 2 & 1 & 0 \ 3 & 2 & 1 \end{vmatrix}$Expanding along the first row:$\det(A) = 1 \begin{vmatrix} 1 & 0 \ 2 & 1 \end{vmatrix} - 0 \begin{vmatrix} 2 & 0 \ 3 & 1 \end{vmatrix} + 1 \begin{vmatrix} 2 & 1 \ 3 & 2 \end{vmatrix}$$\det(A) = 1(1 	imes 1 - 0 	imes 2) - 0 + 1(2 	imes 2 - 1 	imes 3)$$\det(A) = 1(1 - 0) + 1(4 - 3)$$\det(A) = 1(1) + 1(1)$$\det(A) = 1 + 1 = 2$

If $A = \begin{bmatrix} 1 & 0 & 1 \\ 2 & 1 & 0 \\ 3 & 2 & 1 \end{bmatrix}$,then $\det(A)$ is equal to
