Let A be an order 4 square matrix where a1 = and a2 = are the first and second columns of A, respectively. Suppose the nullspace -3 3 a13 a14 a23 a24 of A is spanned by Then the third and forth columns of A are a3 = and a4 = , respectively, where a33 a34 a43 a44 13 = 1 a14 = 2 a23 3 a24 = 4 a33 5 034 = 6 a43 = 7 a44 8 Leave your answer to the nearest 2 decimal place if necessary
