Dividing (multiplying) a row by a constant multiplies (divides) the entire determinant by that constant so to keep the same determinant, do the opposite: if you multiply a row by a constant and divide the determinant by the same constant you do not change the determinant.2)if we divide a row by a constant what do i do to get the right answer for the determinant?
No, "column operations" do exactly the same thing as row operations:3) column operations do not affect the determinant
Multiplying a row or column by a number multiplies the entire determinant by that number.
Swapping two rows or columns multiplies the entire determinant by -1.
Adding a multiple of one row or column to another does not change the value of the determinant.
