Question

how to solve determinants higher than order 3

Answer 1

hi

Answer 2

you have formula for this.

Answer 3

the easiest way is reduce the matrix to get as many number of 0 in a column or a row as possible, the take determinant of new matrix respect to that column and row.

Answer 4

and then, reduce the smaller matrix to get smaller until you get 2x2 or 3x3 matrix which we can easily count determinant
