Question

8950 is equal to 8 by 5 is equal to zero + 8 by 5

Answer 1

the given scalar  triple product is :
[→a →a →b]=→[b →a →a]=→b.(→a×→a) =→b.0=0Here (→a×→a) =∣∣→a∣∣∣∣→a∣∣sin0ˆη=0 because angle between the same vector a is zero.[a→ a→ b→]=[b→ a→ a→]=b→.(a→×a→) =b→.0=0Here (a→×a→) =a→a→sin0η^=0 because angle between the same vector a is zero.

hope this helps you
