For the following matrices verify the associativity of matrix multiplication i.e. (A B)C=A(B C)dot A=[1 2 0-1 0 1] , B=[1 0-1 2 0 3] and C=[1-1] (ii) A=[4 2 3 1 1 2 3 0 1] , B=[1-1 1 0 1 2 2-1 1] and C=[1 2-1 3 0 1 0 0 1] .

If A=[1 1-1 2 0 3 3-1 2] , B=[1 0-1""""""3 2 4] and C=[1 2 3-4 2 0-2 1] , find A(BC), (AB)C and show that (A B)C" "=" "A(B C) .

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=[(2, 3),( 5 ,7)] , B=[(-1 ,0, 2),( 3, 4, 1)] , C=[(-1, 2 ,3),( 2 ,1, 0)] , find A+B and B+C (ii) 2B+3A and 3C-4B .

Statement 1: A=[4 0 4 2 2 2 1 2 1]B^(-1)=[1 3 3 1 4 3 1 3 4] . Then (A B)^(-1) does not exist. Statement 2: Since |A|=0,(A B)^(-1)=B^(-1)A^(-1) is meaning-less.

Find the value of ( ( 1/3 )^(-2) + ( 1/4 )^(-2) ) ÷ ( 1/5 )^(-2) ( a ) 0 ( b ) -1 ( c ) 1 ( d ) 7/5

If A=[[2,-1,5] , [4,0,3]] and B=[[-2,3,1] , [-1,2,-3]] then find A'+B'

If A = [{:(2, -3), (4, 1):}], B = [{:(2, 3), (5, 0):}]" and " C = [{:(-1, 2),(0, 5):}] then find A(B + C).

If A = [[-1, 2 ,3],[-1, 0, 2],[1, -3, 1]] and B = [[4,5,6],[-1, 0, 1], [2,1,2]], find 4A-3B

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
