Question
If A = diag (2, - 1, 3), B = diag (-1, 3, 2), then A2B =
Options
A.diag (5, 4, 11)
B.diag (- 4, 3, 18)
C.diag (3, 1, 8)
D.B
Solution
A = diag (2, -1, 3), B = diag (-1, 3, 2) then A2 B = ?
A =
, B = 
A2 =
A2B =
= diag (- 4, 3, 18)
A =
, B = A2 =
A2B =
= diag (- 4, 3, 18)Create a free account to view solution
