[[4],[1],[3]]A=[[-4,8,4],[-1,2,1],[-3,6,3]]

If [[4],[1],[3]] X= [[-4,8,4],[-1,2,1],[-3,6,3]] , find X.

3.Find the rank of the matrix: [[1,2,3,4],[2,4,6,8],[-1,-2,-2,-4]]

Without expanding prove that: |[12, 2, 4, -5, 1],[-8, 1, -5, 2, -1],[6, 4, a ,-3, 2],[-10, 2, 1 ,3 ,4],[-2, 4, 6 ,8, -5]|=|[12, -4, -8, 10, -2],[4, 1, -5, 2, -1],[-3, 4, a, -3, 2],[5, 2, 1, 3, 4],[1, 4, 6, 8, -5]| .

If the rank of A=[[1,2,3,4],[2,4,6,8],[3,6 ,lambda, mu]] is 1 then lambda+mu

If A=[[1, 2, 3], [3, 4, 5], [4, 6, 8]] , then

Consider the marks obtained by 50 students in a mathematics test for a total marks of 10. 5,8,6,4,2, 5,4,9,10,2, 1,1,3,4,5, 8,6,7,10,2, 1,1,3,4,4, 5,8,6,7,10, 2,8,6,4,2, 5,4,9,10,2, 1,1,3,4,5, 8,6,4,5,8

The rank of the matrix [(1,2,3,4),(2,4,6,8),(-1,-2,-3,-4)] is

The order of the matrices [{:(1,2,3),(4,5,-1):}], [{:(2,4),(9,2),(6,3),(4,1):}] , [{:(4,5,6),(3,2,1),(9,8,7):}] respectively are :

Let U={1,2,3,4,5,6,7,8,9}, A={1,2,3,4}, B=[2,4,6,8], C=[3,4,5,6]. Find: ((A')')'
