# What is the cross product of <-3,0,1> and <0,8,5>?

$< - 8 , 15 , - 24 >$
$\left(- 3 i + k\right) \times \left(8 j + 5 k\right) = \left(- 3 i\right) \times \left(8 j\right) + \left(- 3 i\right) \times \left(5 k\right) + k \times \left(8 j\right) + k \times \left(5 k\right)$
$= - 24 k + 15 j - 8 i + 0$
