    Answer:

    4i+59j+33k

    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 :

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

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