Find the determinant of the matrix, if it exists. (If an answer does not exist, enter DNE.) 1 4 1 64 1 1 8

DNE

Step-by-step explanation:

It must be noted that we can only find the determinant of a square. A square matrix is a matrix that has the same number of row and columns e.g 3×3, 2×2, 4×4 etc

Since the matrix given is not a square matrix, hence the Determinant does not exist (DNE)
