1) What is the component form of resultant of 4b⃗ −2a⃗ ?    *first arrow is on top of b, and second one is on top of a*

     a⃗ =⟨6,−2⟩                *arrow is on top of a*

     b⃗ =⟨−5,2⟩                *arrow is on top of b*

 

    Enter your answer by filling in the boxes.

 

2) What is the product of 3√6cis(π/8) and 2√5cis(7π/6)?

 

 

3) Divide 12(cos(7π/6) + i sin (7π/6)) / 4√6 (cos (3π/4) + i sin (3π/4))

  

 

I have the answers in the boxes, but I want to make sure they're right.
