Answer :
The two vectors are
a' = (3i - 4j + 5k) and b' = (-2i + j + 3k)
So, the required scalar product is
= a' . b'
= (3i - 4j + 5k) . (-2i + j + 3k)
= - 6 - 4 + 15
= 5
and the required vector product is
...| i j k |
= | 3 (-4) 5 |
...| (-2) 1 3 |
= (- 12 - 5)i - (9 + 10)j + (3 - 8)k
= - 17i - 19j - 5k
