Which of the following is/are CORRECT?
A
$vec{p}$ x ($vec{q}$ x $vec{r}$) + $vec{q}$ x ($vec{r}$ x $vec{p}$) + $vec{r}$ x ($vec{p}$ x $vec{q}$) = $vec{0}$
B
$vec{p}$ x ($vec{q}$ x $vec{r}$) = ($vec{p}$ • $vec{r}$) $vec{q}$ - ($vec{p}$ • $vec{q}$) $vec{r}$
C
$vec{p}$ x ($vec{q}$ x $vec{r}$) = ($vec{p}$ x $vec{q}$) x $vec{r}$
D
$vec{r}$ • ($vec{p}$ x $vec{q}$) = ($vec{q}$ x $vec{p}$) • $vec{r}$
