Here is the question
https://prnt.sc/phhsb9
so my guess is do i complete the question by doing this ( 8) ( 3 4 1 1 )
10
7
(12)
Here are the two matrices that we need :
P S
3 4 1 1 8 8 3*8 + 4*10 + 1*7 + 1*12 3*8 + 4*9 + 1*8 + 1*13
6 6 4 6 10 9 = 6*8 + 6*10 + 4*7 + 6*12 6*8 + 6*9 + 4*8 + 6*13 =
2 2 5 4 7 8 2*8 + 2*10 + 5*7 + 4*12 2*8 + 2*9 + 5*8 + 4*13
12 13
83 81
208 212
119 126
thank you very much
