Practice problem
Which of the following matrices can become AAA through row multiplication?
A=[4862−62]A = \begin{bmatrix} 4 & 8 & 6 \\ 2 & -6 & 2 \end{bmatrix}A=[428−662]
A=[12321−31]A = \begin{bmatrix} 1 & 2 & \frac{3}{2} \\ 1 & -3 & 1 \end{bmatrix}A=[112−3231]
A=[1−31243]A = \begin{bmatrix} 1 & -3 & 1 \\ 2 & 4 & 3 \end{bmatrix}A=[12−3413]
A=[243393]A = \begin{bmatrix} 2 & 4 & 3 \\ 3 & 9 & 3 \end{bmatrix}A=[234933]
A=[510152−26−2]A = \begin{bmatrix} 5 & 10 & \frac{15}{2} \\ -2 & 6 & -2 \end{bmatrix}A=[5−2106215−2]
Type a concept, like “slope” or “photosynthesis”.
