If `A=[0 1 2 1 2 3 3a1]a n d A_1=[1//2 12//12//-4 3c5//2-3//2 1//2]` , then the values of `a` anti `c` are equal to `1,1` b. `1,-1` c. `1,2` d. `-1,1`

If A=[(0,1,2),(1,2,3),(3,a,1)] and A^(-1)=[(1//2,-1//2,1//2),(-4,3,c),(5//2,-3//2,1//2)] , then the values of a and c are equal to

Let A d+2B=[1 2 0 6-3 3-5 3 1]a n d2A-B=[2-1 5 0-1 6 0 1 2] . Then T r(B) has the value equal to 0 b. 1 c. 2 d. none

1) If A=[(1,2),(3,4)] , AdjA=[(4,a),(-3,b)] then the values of a and b are ..... a) a=-2, b=1 b) a=2, b=4 c)a=2, b=-1 d) a=1, b=-2

If (FIGURE),the values of a and b are 1,2 (b) 2,3quad (c) 1,3 (d) None of these

If A_1,B_1,C_1, , are respectively, the cofactors of the elements a_1, b_1c_1, , of the determinant "Delta"=|a_1b_1c_1a_1b_2c_2a_3b_3c_3|,"Delta"!=0 , then the value of |B_2C_2B_3C_3| is equal to a1 2 b. a_1 c.a_1^2 d. a1 2^2

If A = {1,2}, B = {1,2,3} and c = {1,2,3,4,5} then the relation between A, B and C?

If A = [(1,2),(3,4)] , adj A = [(4,a),(-3,b)] then value of a and b are : (a) a=-2,b=1 (b) a=2,b=4 (c) a=2,b=-1 (d) a=1,b=-2

If A=[[1,2,-3] , [5,0,2] , [1,-1,1]] and B=[[3,-1,2] , [4,2,5] , [2,0,3]] then find matrix C such that A+2C=B
