Section contains 2 questions. The answer to each of the questions is a single digit integer, ranging from 0 to 9. For see, if the correct answers to question numbers X,Y,Z (say) are 6,0 and 9 respectively, then the correct darkening tables will look like the following :
If `vecx_(1),vecx_(2),vecx_(3)` are two sets of non-coplanar vectors such that `vecx_(r ).vecy_(s)={{:(0","" if "rnes),(2""" if "=s):}` where r,s =1,2,3
what is the value of `[vecx_(1)vecx_(2)vecx_(3)][vecy_(1)vecy_(2)vecy_(3)]` ?
