Oh i was just to upload this question as doubt.
Try pls @pratyaksh_tyagi @Siddhant_Mudholkar @Satyendra_Srivastva
[\vec b\;\vec q\;\vec c]\vec r=[\vec b\;\vec q\;\vec r]\vec c how
Then for [\vec a\;\vec b\;\vec d]\vec c=[\vec a\;\vec b\;\vec c]\vec d
Is this correct @Namish_Garg2
Sorry i am also consfused @Satyendra_Srivastva
One of my friends told me this. But when i took any two vectors such as i, j, k then it doesn't come true
r and c are different vectors ain't they..how could they be equal
No thats incorrect @Satyendra_Srivastva
@Namish_Garg2 your illustration is also wrong.
I think her solution is wrong.
Coz I needed a small method as that opening all would be lengthy to solve this question and when i saw @Silla_Priyadarshni did by opening i didnt read her full solution. But now i noticed this.
Oops I misread it as coplanar vectors
This solution can be correct only in case of coplanar!
