Thank you for the opportunity to help you with your question!

In matrix multiplication , no of rows in first matrix should be equal to no of rows in the second matrix, so in this case, matrix A has 3 rows and matrix B has 3 colomuns, so matrix multiplication is possible

AB=[ 6 x-7 -3x 4 -1 x6 ]

[ 1 x0 2 x7 7 x3 ]

=[ -42 -12 -6 ]

[. 0. 14. 21. ] answer

Please let me know if you need any clarification. I'm always happy to answer your questions.

0. 14. 21. This is the matrix. It has got 2 row and 3 colomuns. You can put the bracket sign.

This full matrix is the answer.

This matrix got 6 elements, 2rows and 3 colomuns, I think now you understand the answer. You can put the bracket sign outside the matrix yourself, in my iPad I can't do, thanks
