Class XII A square matrix A is invertible iff det A is equal to non zero –1 1 0 In a third order determinant , each element of the first column consists of sum of two terms , each element of the second column consists of sum of three terms and each element of the third column consists of sum of four terms . Then it can be decomposed into n determinants , where n has value 1 24 9 16 The system of equationsx+2y =5 , 4x+8y =20 has no solution a unique solution infinitely many solutions none of these. If the entries in a 3 x 3 determinant are either 0 or 1 , then the greatest value of this determinant is : 1 0 None of these 2 If the value of a third order determinant is 11 , then the value of the square of the determinant formed by the cofactors will be 14641 11 1331 121 Do you really want to submit this quiz?
