If A and B are 2-rowed square matrics such that
`(A+B)=[(4,-3),(1,6)] and (A-B)=[(-2,-1),(5,2)]` then AB=?

If A and B are square matrices of the same order such that A^(2)=A,B^(2)=B" and "(A+B)^(2)=A+B," then :"AB=

Give two matrices A and B A=[(1,-2),(1,4)] and B=[(11,-5),(-1,-1)] , Find AB .

If A and B are square matrices of order 3 such that det(A)=-2 and det(B)=4, then : det(2AB)=

If A and B are two square matrices such that AB=BA then (A-B)^(2) =A^(2) - 2AB + B^(2) . True or False.

Show that if A and B are square matrics such that AB=BA , then (A+B)^(2)=A^(2)+2AB+B^(2) .

If A and B are square matrices of order 3 such that "AA"^(T)=3B and 2AB^(-1)=3A^(-1)B , then the value of (|B|^(2))/(16) is equal to

If A and B are square matrices of order 3 such that "AA"^(T)=3B and 2AB^(-1)=3A^(-1)B , then the value of (|B|^(2))/(16) is equal to

Show that , if A and B are square matrices such that AB=BA, then (A+B)^(2)=A^(2)+2AB+B^(2) .

Show that , if A and B are square matrices such that AB=BA, then (A+B)^(2)=A^(2)+2AB+B^(2) .

If A and B are square matrices such that AB = BA then prove that A^(3)-B^(3)=(A-B) (A^(2)+AB+B^(2)) .
