Question

If |A| is not equal to zero. then 'A' is :

1. Singular matrix

2. Non Singular matrix

3. Zero matrix

4. None​

Answer 1

Answer:

singular matrix

Step-by-step explanation:

Singular matrix is square matrix whose determinant is equal to Zero.

So, non-singular matrix A is a matrix whose determinant is non-zero.

⟹ inverse of A i.e. A −1

exist.

∴A −1= ∣A∣adjA

.... [∣A∣ =0]
