Hey there!!
Here's your answer..
You have to remember a basic rule of complex numbers to solve this determinant easily.
The rule is 1 + ω + ω² = 0
Now, coming over to the determinant, we can consider C for a column and R for a row.
Now, let us add C1, C2 and C3, with this the C1 is changed as 1 + ω + ω² in all the three places.
But 1 + ω + ω² = 0. So, the entire C1 is zero.
When a complete column is zero, the value of the determinant is zero.
Zero is the required answer.
Hope it helps!!
