Cho các ma trận A = ( 1 0 3 1 2 − 1 ) và B = ( 1 0 − 1 5 4 2 ) . Tính 2A+3B.

\[2A + 3B = \left( {\begin{array}{*{20}{c}}5&0&1\\{16}&{16}&1\end{array}} \right)\]

\[2A + 3B = \left( {\begin{array}{*{20}{c}}5&2&{14}\\0&{15}&2\end{array}} \right)\]

\[2A + 3B = \left( {\begin{array}{*{20}{c}}6&0&{18}\\0&{16}&3\end{array}} \right)\]

\[2A + 3B = \left( {\begin{array}{*{20}{c}}4&0&{17}\\0&{15}&2\end{array}} \right)\]
