If `A=[[1,2,-3],[2,5,9],[-1,3,5]]` Then find `A^T`

Evaluate the following: If A=[[1,1,-2],[2,1,-3],[5,4,-9]] find |A|

1) If A=[[1,2,3],[4,5,6]] and B=[[1],[9],[8]] ,find AB

If A= [(1,1,3),(5,2,6),(-2,-1,-3)] then find A^(14)+3A-2I

If A=[[1, 1,-2],[ 2, 1,-3],[ 5, 4,-9]] . Find |A| .

Let A=[[1, 1,3], [5, 2,6],[-2,-1,-3]] . Find t r(A^(2012))

(2) If A=[[2,3],[1,5]] then find A^(-1)

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

If A=[(1,-2,3),(4,5,-1),(5,0,2)] find 3A

If A = {1,3,5,7,9} and B = {1,2,3,4,5} then find A cup B and A cap B .

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
