6 10​

Answer 1

$\large\boxed{\begin{array}{l} \begin{bmatrix}2 & 3 \\ 6&10 \end{bmatrix} \\ \\ \rm \: det = 2 \times 10 - 3 \times 6 \\ \\ \rm \: det = 20 - 18 \\ \\ \boxed{\boxed{ \rm{det = 2}}}\end{array}}$

Answer 2

$\Large \text{ \sf{ \begin{bmatrix} \sf2& \sf 3 \\ \sf6 & \sf10 \end{bmatrix}} }$

$\Large \sf{det = 2 \cdot10 - 3 \cdot6 }$

$\Large \sf{det = 20 - 18 }$

$\Large \text{ \boxed{ \boxed{\sf{ det = 2}}} }$
