Question

Find the determinant of the above matrix..
Plsz help...​

Answer 1

Just by looking at the matrix, it becomes clear that each element of row 3 is just double of corresponding element of row 1. Hence if we translate R1--> R1 - R3/2, all elements of the first row will become zero. So the value of determinant is zero
