$left[begin{array}{ccc}1&5&-2\4&0&-1end{array}right] * left[begin{array}{ccc}2&-1\3&6\4&0end{array}right] +7* left[begin{array}{ccc}1&1\0&1end{array}right] T_$       - помогите вычислить матрицу

Answer 1

$left[begin{array}{ccc}1&5&-2\4&0&-1end{array}right]* left[begin{array}{ccc}2&-1\3&6\4&0end{array}right]+ left[begin{array}{ccc}7&0\7&7\end{array}right] = left[begin{array}{ccc}2+15-8&-1+30+0\8+0-4&-4+0+0\end{array}right]+ left[begin{array}{ccc}7&0\7&7\end{array}right]= left[begin{array}{ccc}16&29\11&3\end{array}right]$
