If `A^(-1)=([5,7],[2,3]),` then `A` is

If A=[(3,4,3),(2,5,7),(1,2,3)] then |Adj(Adj A)|=

If A=[[3,4,5],[1,6,7],[2,8,3]] ,then the value of a_(21)A_(11)+a_(22)A_(12)+a_(23)A_(13) is equal to

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

Given that, A=(aij)_(3xx3) =[(1,6,-1),(5,2,7),(1,3,-5)]_(3xx3) then find the values: Where a denote the corresponding elements of the matrix A. 3/2 a_21 +1/2 a_11

Given that, A=(aij)_(3xx3) =[(1,6,-1),(5,2,7),(1,3,-5)]_(3xx3) then find the values: Where a denote the corresponding elements of the matrix A. a_31+a_23+a_33

If A=[[2,3,4],[-3,0,2]], B=[[3,-4,-5],[1,2,1]] and C=[[5,-1,2],[7,0,3]] , find the matrix X such that 2A+3B=X+C

If A={1,2,3} and B={1,3,5,7}, then A uu B={1,2,3,5,7}

If (k,1,5),(1,0,3),(7,-2,l) are collinear then (k,l)
