If `A=[5a-b3 2]` and A adj `A=AA^T` , then `5a+b` is equal to: (1) `-1` (2) 5 (3) 4 (4) 13

If A=[(5a, -b),(3,2)] and A adj A=A A^T, then 5a+b is equal to: (A) -1 (B) 5 (C) 4 (D) 13

If A=|{:(,5a,-b),(,3,2):}| and A adj A=A A^(T) , then 5a+b is equal to

If (5a - 3b) : (4a - 2b) = 2:3, then a:b is equal to: यदि (5a - 3b) : (4a - 2b) = 2:3 है, तो a : b का मान क्या होगा ?

If a : b = 2: 5 , then ( 3a+ 4b) : (5a +6b) is equal to

If A=[{:(2,5),(1,3):}] , find adj A .

Let A=[1 2 3-5] and B=[1 0 0 2] and X be a matrix such that A=B X , then X is equal to 1/2[2 4 3-5] (b) 1/2[-2 4 3 5] (c) [2 4 3-5] (d) none of these

(b) If A^(-1)=[[3,1],[(-5)/(3),(2)/(3)]], then A.adj A is equal to
