[[2,-3],[-1,2]]

If P=[[1,2,-3] , [3,-1,2] , [-2,1,3]], Q=[[2,3,1] ,[3,1,2] , [1,2,3]] then find the matrix R such that P+Q+R is a zero matrix

Check whether the following matrix is invertible or not. [[1,2,3],[2,-1,3],[1,2,3]]

If A=[[1, 2, 3], [2, -1, 3], [1, 2, 3]] , then

Evaluate D =|[2, 3,-2],[ 1, 2, 3],[-2, 1,-3]| by expanding it along the second row.

Evaluate D =|[2, 3,-2],[ 1, 2, 3],[-2, 1,-3]|

Evaluate the determinant D=|[2 ,3,-2],[ 1, 2 ,3],[-2, 1,-3]| by expanding it along first row.
