$\to a x \to b = 20 i - 69 j + 27 k$ $vec a x vec b=20i-69j+27k$

Explanation:

$\to a = < - 3, 4, 8 \to b = < - 9, 3, 1 >$ $vec a=<-3,4,8" "vec b=<-9,3,1>$
$\to a x \to b = i (4 - 24) - j (- 3 + 72) + k (- 9 + 36)$ $vec a x vec b=i(4-24)-j(-3+72)+k(-9+36)$
$\to a x \to b = 20 i - 69 j + 27 k$ $vec a x vec b=20i-69j+27k$
