WebAnd we know that for a two by two matrix, um, the determinant is defined as a d minus BC. And so since we're merely multiplying a times d, which would give you a number since I am dear, both numbers and subtracting that with the product BC this we will no, is definitely a number. And so the determinant is always a scaler, not a matrix. WebInterchange the column or row of Matrices: Yes, by swapping the rows, the determinant will be changed. Let, A = 1 - 2 5 1 is a matrix. Therefore, d e t ( A) = ( 1 + 10) = 11 If we change the rows, then the new matrix will be A ' = 5 1 1 - 2. Here, d e t ( A) = ( - 10 - 1) = - 11 Therefore, swapping the rows change the determinant value. free zenlife games word connect
