Question

What is vector product B×A of two vectors A=7i+4j-8k and B=3i-3j+5k​

Answer 1

`4i+59j+33k`

Step-by-step 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* A=(3i-3j+5k)* (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`.
