જો `A=[0 6 7-6 0 8 7-8 0]` , `B=[0 1 1 1 0 2 1 2 0]` , `C=[2-2 3]` AC, BC અને ગણતરી કરો `(A + B)...

If A=[0 6 7-6 0 8 7-8 0] , B=[0 1 1 1 0 2 1 2 0] , C=[2-2 3] Calculate AC, BC and (A" "+" "B)C . Also, verify that (A" "+" "B)C" "=" "A C" "+" "B C

0.4 x + 0.3 y = 1.7 , 0.7 x - 0.2 y = 0.8

Let A=[(0,6,7),(-6,0,8),(7,-8,0)],B=[(0,1,1),(1,0,2),(1,2,0)],C=[(2),(-2),(3)] . Calculate AC, BC and (A+B)C. Also show that (A+B)C=AC+BC.

Show that A B!=B A in each of the following cases: A=[5-1 6 7] and B=[2 1 3 4] (ii) A=[-1 1 0 0-1 1 2 3 4] and B=[1 2 3 0 1 0 1 1 0] (iii) A=[1 3 0 1 1 0 4 1 0] and B=[0 1 0 1 0 0 0 5 1]

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

In the following number series how many 0's are there which are immediately preceded by a pair of numbers whose product is more than the product of the pair of numbers immediately following it ? 4 8 0 9 2 5 0 3 0 1 9 6 0 4 3 7 8 0 3 2 4 0 3 2 0 0 9 8 6 2 0 5 3 1) 4 2) 5 3) 6 4) 2 5) None of these

Show that(i) [[5,-1],[ 6 ,7]][[2, 1],[ 3 ,4]]!=[[2, 1],[ 3, 4]][[5,-1],[ 6, 7]] (ii) [[1, 2, 3],[ 0, 1, 0],[ 1, 1, 0]][[-1, 1, 0],[ 0,-1, 1],[ 2, 3, 4]]!=[[-1, 1, 0],[ 0,-1, 1],[ 2, 3, 4]][[1 ,2 ,3],[ 0, 1, 0],[ 1, 1, 0]]
