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 det[[a+ib,c+id-c+id,a-ib]]

If A = [(a+ib,c+id),(-c+id,a-ib)], a^(2)+b^(2)+c^(2)+d^(2) =1 , then find inverse of A.

If A=[(a+ib,c+id),(-c+id,a-ib)] and a^(2)+b^(2)+c^(2)+d^(2)=1 , then A^(-1) is equal to

If A=[(a+ib,c+id),(-c+id,a-ib)] and a^(2)+b^(2)+c^(2)+d^(2)=1 , then A^(-1) is equal to

If A=[(a+ib,c+id),(-c+id,a-ib)] and a^(2)+b^(2)+c^(2)+d^(2)=1 , then A^(-1) is equal to
