  1. Dot product
    Find the dot product of the following ordered nn-tuples:
    1. a⃗=(2,4,6) \vec{a}=(2,4,6) and b⃗=(1,3,5)\vec{b}=(1,3,5)
    2. a⃗=(1,7,5,3) \vec{a}=(1,7,5,3) and b⃗=(−2,3,6,1)\vec{b}=(-2,3,6,1)
    3. a⃗=(1,2) \vec{a}=(1,2) and b⃗=(3,5)\vec{b}=(3,5)
    4. a⃗=(7,−2,−1,4) \vec{a}=(7,-2,-1,4) and b⃗=(1,1,2,2)\vec{b}=(1,1,2,2)
