Explain solution RD Sharma class 12 chapter 4 Algebra of Matrices exercise Fill in the blank question 32 maths

Answers (1)

Answer:

A^-1does not exist

Hint:

We must be aware with elementary row operations

Given:

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

Solution:

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^-1does not exist
