Example 7 If A = [ 8(1&2&[email protected]&3&1)] and B = [ 8(3& 1&[email protected] 1&0&2)] then find 2A B. Finding 2A 2A = 2 [ 8(1&2&[email protected]&3&1)] = [ 8(2 1&2 2&2 [email protected] 2&2 3&2 1)] = [ 8(2&4&[email protected]&6&2)] Now, finding 2A B 2A B = [ 8(2&4&[email protected]&6&2)] [ 8(3& 1&[email protected] 1&0&2)] = [ 8(2 3&4 ( 1)&6 [email protected] ( 1)&6 0&2 2)] = [ 8( 1&4+1&[email protected]+1&6&0)]
