Question

Help me on this sum from chapter matrices.​

Answer 1

Answer:

In first matrix

= 4*1/2      2*1/2

  1               2

= 2         1

  1          2

Now multiply both matrix

Therefore,

= 2*4 + 2*5        1*5 + 1*4

  1*4 + 1*5          2*5 + 2*4

= 8+10       5+4

  4+5         10+8

=  18       9

    9        18

Hope this helps you
