(\overrightarrow{a} \times \overrightarrow{b}) \cdot( \overrightarrow{c}\times \overrightarrow{d}) is equal to

\overrightarrow{a} \\overrightarrow{ {b} \times (\overrightarrow{c} \times \overrightarrow{d})\}

(\overrightarrow{a} \times \overrightarrow{b}) \times \overrightarrow{c}\} \cdot \overrightarrow{d}

(\overrightarrow{a \cdot c})(\overrightarrow{b} \cdot \overrightarrow{d})-(\overrightarrow{a} \cdot \overrightarrow{d})(\overrightarrow{b} \cdot \overrightarrow{c})

(\overrightarrow{d} \times \overrightarrow{c}) \cdot(\overrightarrow{b} \times \overrightarrow{a})
