Answer
$-9i-7j -3k$
Work Step by Step
Let us consider two vectors $v=xi+yj+zk$ and $w=pi+qj+rk$. Then cross product of the two vectors $v$ and $w$ can be computed in the form of determinant as:
$ v \times w=\begin{vmatrix}
i & j & k \\
x & y & z \\
p & q & r \\ \end{vmatrix}$
We have:
$det =u \times v =[(-3)(2)-(1)(3)] i -j [(2)(2) - (1)(-3)]+k [(2)(3) -(-3) (-3)]=-9i-7j -3k$
