WebEvaluate the determinant of the matrix in Exercise 13 by a cofactor expansion along (a) the first row. (b) the first column. (c) the second row. (d) the second column. (e) the third row. (f) the third column. Answer: 20. Evaluate the determinant of the matrix in Exercise 12 by a cofactor expansion along (a) the first row. (b) the first column. Weband the second row of A is [2 4 6 8 ··· 2n]. Thus, the first two rows of A are linearly dependent, meaning that A is singular since elim-ination will produce a row of all zeros in the second row. Thus, the determinant of A must be zero. (In fact, every row is a multiple of the first row, so A is about as far as a non-zero rabbit knowledge
