1.Find vectors v*w if vector v = 5 vector i – 4 vector j + 4 vector k and vector w = –6 vector i + 3 vector j – 2 vector k.
2.Find vectors v*w if vector v = 3 vector i – 4 vector j  8 vector k and vector w = 2 vector i + 6 vector j + 4 vector k.

v*w has no meaning in common notation.
Do you mean v•w or v×w ? 
v times w

i assume you mean crossproduct
I'll do #1:
vxw =
 i j k
5 4 4 
6 3 2
= 32i28j+26k
You can make things a lot more readable by just saying you're dealing with vectors. Then you can forget about all those words and just write the values, as in my answer. 
no i don't mean cross product.
3– 4– 2
–14– 9– 4
5+ 3– 4
–4– 14– 9
these are the possible answers. all with IJK following of course. 
In that case, say dot product.
5i4j+4k • 5i+3j2k = 25128 = 45
you say you don't mean cross product, but you give vectors for answers.
dot product of two vectors is just a number.
I'm afraid I don't know what operation you are using.
