`|[1,3,7],[7,5,9],[2,0,1]|=?`

1) the value of |[5,6,7],[0,2,9],[0,0,3]| is

A= [[-2,5,7] , [0,3,2], [9,4,1]] Find A' and |A|

Find the rank of A=[[1,2,0],[3,7,1],[5,9,3]]

If A=[[1,0,5],[3,2,7],[5,4,8]],B=[[3,1,2],[9,0,-6],[7,4,1]],C=[[2,0,-1],[7,5,6],[1,1,4]] , verify that A+(B+C)=(A+B)+C

Write the following as a single matrix: [1,-2,3] [[2,-1,5], [0,2,4],[-7,5,0]] -[2,-5,7]

If A=[(3,9,0),(1,8,-2),(7,5,4)], B=[(4,0,2),(7,1,4),(2,2,6)] , verify that 3(A+B)=3A+3B .

If A=[[1,4],[0,5],[6,7]] and B=[[2,3,-1],[1,0,-7]] , verify that (AB)\'=B\'A\'

If x={0,1,2,3,4,5,6,7,8,9,10} and Y={ 1,3,5,7,9} then X-Y=___.
