If A = [ (1,2,2),(2,1,-2),(a,2,b)] is a matrix satifying the equation "AA"^(T)= 9I where I is a 3xx3 identify matrix , thenthe ordered pair (a,b) is equal to :

If A=[(1,2,2),(2,1,-2),(a,2,b)] is a matrix satisying the equation A A^(T)=9I , where I is 3xx3 identity matrix, then the ordered pair (a, b) is equal to

If A = [(1,2,2),(2,1,-2),(a,2,b)] is a matrix satisfying the equation "AA"^(T) = 9I , where I is 3xx3 identity matrix, then the ordered pair (a,b) is equal to

If A=((1, 2,2),(2,1,-2),(a,2,b)) is a matrix satisfying the equation A A^(T) =9I , where I is 3xx3 identity matrix, then the ordered pair (a, b) is equal to

If A=[(1,2,2),(2,1,-2),(a,2,b)] is a matrix satisfying the equation A A^T=9I , where I is 3xx3 identity matrix, then the ordered pair (a,b) is equal to : (A) (2,-1) (B) (-2,1) (C) (2, 1) (D) (-2,-1)

Select the correct options from the given alternatives:If A=[[1,2,2],[2,1,-2],[a,2,b]] is a matrix satisfying the equation A.A^T=9I ,where I is the identity matrix of order 3,then the paired (a,b) is equal to

If A=[(1,2,2),(2,1,-2),(x,2,y)] is a matrix such that "AA"^(T) =9I , find the values of x and y.

If A=[1 2 2 2 1-2a2b] is a matrix satisfying the equation AA^T=""9I , where I is 3xx3 identity matrix, then the ordered pair (a, b) is equal to : (1) (2,-1) (2) (-2,""1) (3) (2, 1) (4) (-2,-1)

If A=[1 2 2 2 1-2a2b] is a matrix satisfying the equation AA^T=""9I , where I is 3xx3 identity matrix, then the ordered pair (a, b) is equal to : (1) (2,-1) (2) (-2,""1) (3) (2, 1) (4) (-2,-1)
