Answer
equation is incorrect or meaningless
Work Step by Step
İn order equation like $\overrightarrow {x}\times \overrightarrow {y}$ or $\overrightarrow {x}\cdot \overrightarrow {y}$ to be correct or meaningfull both left and right side of equation must be vectorial
So lets look at left and right sides:
$\overrightarrow {A}\times \left( \overrightarrow {B}\cdot \overrightarrow {C}\right) $ right side is vectorial but left side is scalar product so this equation is incorrect or meaningless
