Question

Solve this matrix problem.

Answer 1

When the determinant for a square matrix is equal to zero, the inverse for that matrix does not exist .

So,
det (A) = 0 (1)
But , determinant of matrix is :
det (A) = ( 4 x k ) - ( 3 x 2 )
Now , by (1) ,
( 4 x k ) - ( 3 x 2 ) = 0
4k - 6 = 0
4k = 6
k = 6/4
k = 3/2

Answer 2

Hi...☺

Here is your answer...✌
===================================

Inverse of matrix A doesn't exist

=> |A| = 0

(k×4) - (2×3) = 0

4k-6 = 0

4k = 6

k = 6/4

k = 3/2
