`[{:(3,, - 1 ), (-4,,2):}] `

If A = [(2,2,1), (1,3,1), (1,2,2)] then A^-1+(A-5I) (AI)^2 = (i) 1/ 5 [[4,2, -1], [-1,3,1], [-1,2,4]] (ii) 1/5 [[4, -2, -1], [-1, 3, -1], [-1, -2,4]] (iii) 1/3 [[4,2, -1], [-1,3,1], [-1,2,4]] (iv) 1/3 [[4, -2, -1], [-1,3, -1], [-1, -2,4]]

The matrix A = [{:(2 , -2, -4),(- 1, 3, 4),(1 , - 2, -3):}] is

Find |A|: A = {:[(2,1,5),(3,-2,-4),(-3,1,-2)]

|{:(1,-3,2),(4,-1,2),(3," "5,2):}|

The centroid of the tetrahedron whose vertices are (4,1,-2), (-3,3,-4),(-3,2,1),(4,2,3)

If A=[(2,-2,-4),(-1,3,4),(1,-2,-3)] then A is

|{:(" "1," "4,-3),(-4," "1," "2),(" "3,-2," "1):}|

Match the following Columns {:(, ,A,B,C,D),(,(a),1,2,3,4),(,(b),1,2,4,3),(,(c),3,4,1,2),(,(d),3,4,2,1):}

3 3)/(4)-1(1)/(2)=?
