I have been lost in this forever due to missing the lecture, but does anybody know how to do this? Thank you for the help if you can.
a=3.0i+3.0j-2.0k
b=-1.0i-4.0j+2.0k
c=2.0i+2.0j+1.0k
The question is: a(dot)(axb)=?

What you are asked to evaluate here is what is know as the scalar triple product.
I understand the b+c part, but I'm not sure on how you find the dot product of a and what (b+c) creates.
When you take the dot product of a and this new vector (b+c), we get a scalar value. You multiply the like components together, and then add them all together. Note that
