Let `a=[(1,-1),(2, -1)] and B=[(a,1),(b,-1)]` are two matrices. If `(A+B)^(2)=A^(2)+B^(2)`, then the value of `3a+4b` is equal to

If A=[[a,b],[-1,2]],B=[[1,1],[2,4]] and (A+B)(A-B)=A^(2)-B^(2) , then the value of a+b equals

Let A =[(2,-1,1),(-1,2,-1),(1,-1,2)] "and" 4B=[(3,1,-1),(1,3,x),(-1,1,3)] . If B is the inverse of A, then the value of x is

let a=([1,-12,-1]), and B=([1,a4,b]) if (A+B)^(2)=A^(2)+B^(2) then (a,b)

A=[[1,1],[0,1]] and B=[[b_(1),b_(2)],[b_(3),b_(4)]] are two matrices such that , 10(A^(10))+adj(A^(10))=B .What is the value of sum_(k=1)^(4)b_(k) ?

Let A and B are square matrices of order 3. If |A|=4, |B|=6, B=A-2I and |adj(I-2A^(-1))|=k , then the value of k is equal to
