Answer:
AB = 4i - 2j + 9k
Explanation:
AB = OA + OB
AB = ( 2i +3j +6k ) + ( 2i - 5j+3k )
AB = 2i + 2i+3j - 5j+ 6k + 3k
AB = 4i - 2j + 9k

Answer:
AB = 4i - 2j + 9k
Explanation:
Given: ŌA = 2i +3j +6k, OB=2i - 5j+3k
To find: The resultant vector
AB = OA + OB
AB = ( 2i +3j +6k ) + ( 2i - 5j+3k )
AB = 2i + 2i+3j - 5j+ 6k + 3k
AB = 4i - 2j + 9k
