## Homework Statement

vector a = (4i+3j-2k)

vector b = (2i-3j+2k)

1. a x b

2. 3a x 2b

3. |3a x 2b|

## The Attempt at a Solution

1. -12j - 18k

2. 6(a x b)

6(-12j - 18k)

-48j -108k

3. |6(a x b)|

sqrt(48^2 + 108^2)

sqrt(13968)

idk if I am using identities wrong or if I am way off, thanks for confirmation on right/wrong and any help
