2
\( (\mathrm{A}+\mathrm{B})^{\mathrm{T}}=\left[\begin{array}{ll} 4 & 1 \\ 3 & 9 \end{array}\right] \)
3
\( \mathrm{A}^{\mathrm{T}} \mathrm{B}=\left[\begin{array}{cc} 0 & 4 \\ 10 & 20 \end{array}\right] \)
4
\( \mathrm{A}^{\mathrm{T}} \mathrm{B}^{\mathrm{T}}=\left[\begin{array}{cc} 4 & 2 \\ 6 & 23 \end{array}\right] \)
