Question

answer plz what the value of the determinant?​

Answer 1

Step-by-step explanation:

We know that

w

2

+w+1=0

w

3

=1

Now, Expanding the given Determinant

1(w

2

−w)−w(w−w

2

)+w

2

(w

2

−w

4

)=w

2

−w−w

2

+w

3

+w

4

−w

6

=−w+1+w

4

−1

2

=−w+w

4

=−w+w.w

3

=−w+w.1=−w+w=0
