If `A=[(0,0),(0,0)] B = [(a_(11),a_(12),a_(13),a_(14)),(a_(21),a_(22),a_(23),a_(24))]` and AB =C. Find the matrix C.

If |A| = |(a_(11), a_(12), a_(13)),(a_(21),a_(22),a_(23)),(a_(31),a_(32),a_(33))| = 6 , then write down the value of |A^(-1)| .

If A=[(0,a),(0,0)] and B = [(b,0),(0,0)] , then find AB.

If A=[(1,0,-1),(2,1,0)], B=[(3,1),(-1,2),(0,1)] and C=[(4,2),(-3,0),(1,2)] show that AB=AC .

If A=[(2,0),(1,4)] and B=[(-1,2),(3,0)] , then find (AB)'.

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

If A^(-1) =[(0,1),(1,0)] and B^(-1) =[(1,0),(0,1)] , then find (AB)^(-1)
