Step-by-step explanation:
Given:
To find:What should be the value of x so that the matrix A does not have an inverse?
Solution: We know that if matrix A is Singular matrix
i.e. Determinant of A is zero, then A does not have an Inverse.
Or A is not invertible.
Now for the given matrix A,
|A|=0
so, value of x should be
Thus,
if x= 16,
then matrix doesn't have an inverse.
Hope it helps you.
