If `A = [ [ 1 , 2 ] , [ 4 , -3 ] ]` , then find `A^2`

If A=[[1,-2,3],[0,-1,4],[-2,2,1]], then find |A| .

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

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

If A*[[3,2],[1,-1]]=[[4,1],[2,3]] " then find A .

If A=[[1,1,2],[2,1,3],[5,4,9]] then find |A|

If A=[(1,-2),(-3,4)] , then find A^(2)+5A .

If A=[[3, -1, 4], [2, 3, 1]], B=[[1, 3, 4], [2, 1, 0], [-3, 2, 3]] find AB

If A = [(0,4,3),(1,-3,-3),(-1,4,4)] , then find A^(2) and hence find A^(-1)

Find the value of | [ 2 , 4 ] , [ 1 , 3 ] | + | [ 4 , 1 ] , [ 1 , 3 ] | + | [ 3 , 3 ] , [ 1 , 3 ] | + | [ 1 , 2 ] , [ 1 , 3 ] |

" (a) If "A=[[1,1,2],[2,1,3],[5,4,9]]" then find "|A|
