Answer:

The cross product is #[44,10,-16]#.

Explanation:

Let us consider [0,8,5] as #vecA=8hatj+5hatk# and similarly [2,4,8] as #vecB=2hati+4hatj+8hatk#.
So, the cross product of these two vectors is #vecAxxvecB#,
#vecAxxvecB=hati[64-20}-hatj[0-10]+hatk[0-16] =44hati+10hatj-16hatk#.
#:.#The cross product of #[0,8,5]# and#[2,4,8]# is #[44,10,-16]#.
