1. u,v, w are not given.

Times? What is times? Do you mean the cross product?

Your use of the word times indicates to me that you need to urgently review what dot product and cross product mean. There is no vector operation "times".

3. Bob,

Here is the entire question:

Use vectors u, v and w given below to find each expression.

(1) v X w

(2) v X u

(3) (u X v) X w

u = 2i - 3j + k
v = -3i + 3j + 2k
w = 1 + j + 3k
