Question

If ∣A∣ = 0 then matrix A is called:

a. Singular matrix
b. non-singular matrix
c. square matrix
d. none of these

Answer 1

If ∣A∣ = 0 then matrix A is called:

Step-by-step explanation:

a. Singular matrix

Answer 2

Answer:

If ∣A∣ = 0 then matrix A is called Singular matrix.

Step-by-step explanation:

• A singular matrix is a square matrix if its determinant is 0. i.e., a square matrix A is singular if and only if det A = 0.
• A singular matrix's determinant is zero.
• When the determinant of a matrix is zero, we cannot discover its inverse, which is referred to as a non-invertible matrix.
• Only square matrices are defined as singular.
• This matrix will not have a multiplicative inverse.
