If `A=[[9,7,6],[7,-1,8],[3,4,2]]`, then `|A|=?`

Find the rank of the matrix A=[[9,7,3,6],[5,-1,4,1],[6,8,2,4]]

The co-factor of -4 and 9 in [[-1, -2, 3], [-4, -5, -6], [-7, 8, 9]] are respectively.

If A = {1,2,3……..9} , B = {2,4,6,7,8} and C = {3,4,5,8,9,10} then (A - B) uu C is .

If A={1,2,3,4,5,6,7,8} and B={1,3,5,6,7,8,9}, then A-B={2,4},B-A={9}

If U = {1,2,3,4,5,6,7,8,9} and A = {1,2,3,4} , then (A^(c))^(c) = ……….. .

If A={1,4, 7,8}, B={4,6,8,9} and C={3,4,5, 7} be three subsets of a universal set U ={1,2, 3, 4,5, 6, 7,8, 9} . Then, A uu (Bnn C') is equal to

If A=[(3,9,0),(1,8,-2),(7,5,4)], B=[(4,0,2),(7,1,4),(2,2,6)] , verify that 3(A+B)=3A+3B .

If U= {1,2,3,4,5,6,7,8,9,10} and A= {3,4,7,9}, then B equals :

If x={0,1,2,3,4,5,6,7,8,9,10} and Y={ 1,3,5,7,9} then X-Y=___.
