MATH 17100 28446 Quiz 17 solution 11/18/ 2009 1. Evaluate the following determinant by using the Laplace Expansion Method (1 row st expansion). Which row or column expansion would involve the least amount of work? 11 12 13 2 13 16 1 1 6 2( 1) ( 1)( 1) 3( 1) 20 00 02 020 + ++ = +− − + − 2[1(0) 2(6)] [1(0) 6(0)] 3[1(2) 1(0)] = +− + 2( 12) 0 3(2) = 18 = − Expansion by 3 rd row would entail least amount of work due to the two 0 entries. 2.
