    If all elements of a row (or column) of a determinant are multiplied by some scalar number k, the value of the new determinant is k times of the given determinant.

    Let the determinant of the given matrix be det(A)

    When the matrix is multiplied by 5, then det(5A) will be: 5*det(A)

    I hope my answer helps. All the very best for your future endeavors!
