1. The problem statement, all variables and given/known data If d1 = 4i - 10j + 2k and d2 = 9i - 10j + 6k, then what is (d1 + d2) · (d1 × 4d2)? 2. Relevant equations Know how to do the cross product and dot product 3. The attempt at a solution For the answer i got 9.6i + 56j -127.68k. How do i express that as a scalar for an online program that only has one box to type in?
