If A = and A² + kI = 8A, then k equals

If A and B are matrices of order m × n and n × n respectively, then which of the following are defined-

the products (A) and (B) are:

A matrix A = (aij) m x n is said to be a square matrix if-

For any square matrix A = [aij], aij = 0, when i  j, then A is-

The multiplicative inverse of A =is

 (A) and (B) are:

A = , then A³ – 4A² – 6A is equal to -

Inverse of the matrix is

If A = and A² – 4A – n I = 0, then n is equal to

The value of x for which the matrix product  equal an identity matrix is :

If A = , then A^–1 is equal to :

If A is a singular matrix, then adj A is :

Statement - I The value of x for which (sin x + cos x)^{1 + sin 2x} = 2, when 0 ≤ x ≤ , is  only.

Statement - II The maximum value of sin x + cos x occurs when x =

In this question, we have to find the statements are the correct or not and statement 2 is correct explanation or not, is same as assertion and reason.

If [1 2 3 ]A = [4 5], the order of matrix A is :

Let A and B be 3 × 3 matrices, then AB = O implies:
