Answers (1)


 A-1 does not exist


 We must be aware with elementary row operations


 A^{-1}=\frac{a d j A}{|A|},|A| \neq 0


A-1 by elementary row operations we obtain all zero in one or more

So, if any one row or column has zero or all the element of a row or column is zero

So, |A| = 0

 So, A-1 does not exist
