if A=[(1,2,2),(2,1,-2),(a,2,b)] is a matrix satisfying A A'=9I_(3,) find the value of |a|+|b|.

if A=[(1,2,2),(2,1,-2),(a,2,b)] is a matrix satisfying A A'=9I_(3,) find the value of |a|+|b|.

if A=[(1,2,2),(2,1,-2),(a,2,b)] is a matrix satisfying A A'=9I_(3,) find the value of |a|+|b|.

if A=[(1,2,3),(2,1,-1),(a,2,b)] is a matrix satisfying A A'=9I_(3,) find the value of |a|+|b|.

if A=[(1,2,3),(2,1,-1),(a,2,b)] is a matrix satisfying A A'=9I_(3,) find the value of |a|+|b|.

If A=(1)/(3)[[1,2,22,1,-2a,2,b]] is an orthogonal ,b=-1 d.b=1

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)

If A=[(1 2 2)[, (2 1 -2),(a 2 b)] is a matrix satisfying A A^T=9I_3 , then find the values of a and b .

If A = [(1,2,2),(2,1,-2),(a,2,b)] is a matrix satisfying A A^(T) = 9I_(3) , then the values of a and b are respectively A)1, 2 B) -1, 2 C) -1, -2 D) -2, -1
