8. Vectors

If vectors $v ⃗=⟨3,1,0⟩$, $u ⃗=⟨0,-2,0⟩$, and $w ⃗=v ⃗×u ⃗$, find $w⃗⃗$.

If vectors $a⃗=5î$, $b⃗=12k̂$ and $c⃗=a⃗\(\times\) b⃗$ , find $c⃗$.

Given the vectors $i$ and $j$, compute $(i\times j)\times k$ using the properties of cross products (not determinants). Which of the following is the result?
