If A=[(1,2)], B= [(1),(2)] , then AB =

If A=[{:(1,2),(-1,-2):}], B=[{:(2,a),(-1,b):}] and (A+B)^(2) =A^(2) + B^(2) , then find the value of a and b.

A=[[1,-12,-1]],B=[[a,1b,-1]] and (A+B)^(2)=A^(2)+B^(2), find a and b

If A = [(-1,2),(3,1)],B=[(1,0),(-1,0)] then the value of 2A+B+2I=

If A=[(2 ,3,-5 ),(1, 2,-1)] and B=[(0, 5,1),(-2, 7, 3)] , find A+B and A-B

If A=[1-12-1],B=[a1b-1] and (A+B)^(2)=A^(2)+B^(2), find a and b

2) If A=[(1,2),(5,7)],B=[(2,1),(3,4)] , find AB.

If A={:[(2,-3),(1,2)]:}andB={:[(3,2),(7,-1)]:} , find matrix C such that C=AB+A^(2)B .

If A = [(1,2),(3,4)] , adj A = [(4,a),(-3,b)] then value of a and b are : (a) a=-2,b=1 (b) a=2,b=4 (c) a=2,b=-1 (d) a=1,b=-2
