For a given matrix, `p=[ [2, -4],[ -6, 7 ] ]` find the trace of the matrix p

In the matrix A= [(2,-1,3),(4,6,1) ] ,write the order of the matrix

[{:(2,3),(5,7):}] find the inverse of the matrix

A is a square matrix of order n. l = maximum number of distinct entries if A is a triangular matrix m = maximum number of distinct entries if A is a diagonal matrix p = minimum number of zeroes if A is a triangular matrix If l + 5 = p + 2 m , find the order of the matrix.

If n=p , then the order of the matrix 7X-5Z is :

[{:(1,3),(2,7):}] find the inverse of matrix

[{:(3,10),(2,7):}] find the inverse of matrix

[{:(2,-6),( 1,-2):}] find inverse of matrix

Find the adjoint of matrix A=[[5,-1],[2,7]]

If the trace of the matrix A is 4 and the trace of matrix B is 7, the find trace of the matrix AB.

If the trace of the matrix A is 5, and the trace of the matrix B is 7, then find the matrix (3A + 2B).
