First open each small bracket with vector product rule
Then u will get two term in place of one
Among the two second will be with negative sign
Then open first two according to determinant rule
Do the same way with the other two
U will see 8 box with three terms will be there
Some box value will be 0 and 2 will left
After changing one of them by interchange rule both will be equal and get cancelled
