Answer 2

Step-by-step explanation:

$\large{\boxed{\pink{\bold{ A B = \left[ \begin{array} { l l } { 1 } & { 0 } \\ { 2 } & { 0 } \end{array} \right] \left[ \begin{array} { l l } { 0 } & { 0 } \\ { 1 } & { 2 } \end{array} \right] = \left[ \begin{array} { l l } { 0 + 0 } & { 0 + 0 } \\ { 0 + 0 } & { 0 + 0 } \end{array} \right] = \left[ \begin{array} { l l } { 0 } & { 0 } \\ { 0 } & { 0 } \end{array} \right] = 0 }}}}$

$\large{\boxed{\pink{\bold{ B A = \begin{bmatrix} \begin{array} { l l } { 0 } & { 0 } \\ { 1 } & { 2 } \end{array} \end{bmatrix} \begin{bmatrix} \begin{array} { l l } { 1 } & { 0 } \\ { 2 } & { 0 } \end{array} \end{bmatrix} = \begin{bmatrix} \begin{array} { l l } { 0 + 0 } & { 0 + 0 } \\ { 1 + 4 } & { 0 + 0 } \end{array} \end{bmatrix} = \begin{bmatrix} \begin{array} { l l } { 0 } & { 0 } \\ { 5 } & { 0 } \end{array} \end{bmatrix} ≠0 }}}}$
