[3 points] compute the following and write your answer in the form a + bi, a, b r. = (2 + 3i)(3 i) (4i)( 3) = 6 2i + 9i + 3 + 12i = 9 + 19i (b) Note that more than one statement may be true. What is a11 a12 a13 a21 a22 a23 a31 a32 a33. Solution: since the second matrix is obtained from the rst by multiplying the. Solution: we have det( 2b 1at cb t ) = det i = 1. = ( 2)4(det b) 1(det at )(det c)(det b t ) = 1. [5 points] compute the determinant of the matrix.
