A) \[\mathbf{u}\,.\,(\mathbf{v}\times \mathbf{w})\]
B) \[(\mathbf{u}\,.\,\mathbf{v})\,.\,\mathbf{w}\]
C) \[(\mathbf{u}\,.\,\mathbf{v})\,\mathbf{w}\]
D) \[\mathbf{u}\times (\mathbf{v}\,.\,\mathbf{w})\]
Correct Answer: A
Solution :
Since \[(\mathbf{u}\,.\,\mathbf{v})\] is scalar and scalar dot or cross product are not defined for options b and d. So answers are a and c.
