Answer 1

Answer:

because it will become identity and according to identity property whole matrix become zero i two rows or two columns are same

Step-by-step explanation:

for example

given matrix of 3×3

here it can be identity by taking 2 common from column 3 aur from taking 3 common from Row 3

• by taking 3 common from r 3
