Inverse using elementary operations
bro @Sarvesh_Pnchl how to know the correct way to do these kind of problems
i m always stuck
is there any trick or definite sequential way
i practiced many problems with this only try any problem you will get it
What is written after and then it with
and then it will be doable.
Similarly do 15.
Step by step make identity matrix on LHS. Eventually you will get the inverse on RHS.
Select any of the three columns first and make it look like the colon of an identity matrix. ( I prefer 1st column )
Then do the same for other 2 columns.
Please do 15
