$\to B = (- 4, 11, 4)$ $vec B=(-4,11,4)$

Explanation:

$\to A = (a, b, c)$ $vec A=(a,b,c)$
$\to B = (d, e, f)$ $vec B=(d,e,f)$
$\to A X \to B = (b \cdot f - c \cdot e, a \cdot f - c \cdot d, a \cdot e - b \cdot d)$ $vec A X vec B=(b*f-c*e ,a*f-c*d,a*e-b*d)$
$\to A = (- 3, 4, 8)$ $vec A=(-3,4,8)$
$\to B = (2, - 4, - 9)$ $vec B=(2,-4,-9)$
$\to A X \to B = (- 36 - + 32), (27 - 16), (12 - 8)$ $vec A X vec B=(-36-+32),(27-16),(12-8)$
$\to B = (- 4, 11, 4)$ $vec B=(-4,11,4)$
