Answer:

[tex]4i+59j+33k[/tex]

Explanation:

Given that,

Vector A = 7i+4j-8k

vector B = 3i-3j+5k​

We need to find B×A. It can be calculated as follows :

[tex]B\times A=(3i-3j+5k)\times (7i+4j-8k)\\\\=i (24 - 20) - j (-24 - 35) + k (12 + 21) \\\\=4i+59j+33k[/tex]

So, the value of vector product is [tex]4i+59j+33k[/tex].
