if `|{:(a+ib,c+id),(-c+id,a-ib):}|xx|{:(alpha-ibeta,gamma-idelta),(-gamma-idelta,alpha+ibeta):}|=|{:(A-iB,C-iD),(-C-iD,A+iB):}|` ,show that the producrs of sums , each of four squares , can be expressed as the sum of four squares.

If |[a+ib,c+id],[-c+id,a-ib]|**|[alpha-ibeta,gamma-idelta],[-gamma-idelta,alpha+ibeta]|= |[A-iB,C-iD],[-C-iD,A+iB]| write down the values of A,B,C,D , hence show that the producrs of sums , each of four squares , can be expressed as the sum of four squares

Evaluate: |(a+ib,c+id),(-c+id,a-id)|

Evaluate: |{:(" "a+ib,c+id),(-c+id,a-ib):}|

if a+ib=c+id , then

Evaluate |(a+ib,c+id),(-c+id,a-ib)| where i=sqrt(-1)

If a + ib = c + id , then

If a + ib = c + id , then

If a+ib=c+id , then
