Answer 1

Answer:

Please mark me as brainliest

Step-by-step explanation:

We have a 3×2 matrix A.

A=[aij]  

3×2

​

 has 3 rows & 2

Columns  

A=  

⎣

⎢

⎢

⎡

​

 

a  

11

​

 

a  

21

​

 

a  

31

​

 

​

 

a  

12

​

 

a  

22

​

 

a  

32

​

 

​

 

⎦

⎥

⎥

⎤

​

 

3×2.

​

 , here aij=2i−j

So, a  

11

​

=2(1)−(1)=1

a  

12

​

=2(1)−(2)=0

a  

21

​

=2(2)−(1)=3

a  

22

​

=2(2)−(2)=2

a  

31

​

=2(3)−(1)=5

a  

32

​

=2(3)−(2)=4

So, A=  

⎣

⎢

⎢

⎡

​

 

1

3

5

​

 

0

2

4

​

 

⎦

⎥

⎥

⎤

​

 

3×2.
