Chapter 2 Matrices Ex 2.1

Question 1.
Apply the given elementary transformation on each of the following matrices.
word image 18872 1

Question 3.
word image 18872 2

Question 4.
word image 18872 3
word image 18872 4

Question 5.
word image 18872 5

Question 6.
word image 18872 6
We conclude from Ex. 5 and Ex. 6 that the matrix remains same by interchanging the order of the elementary transformations. Hence, the transformations are commutative.
