Answer:

P + Q = 4i^-2j^+2k^

Step By Step Explanation:

Vectors can be added only along their components. Meaning the given vectors of P and Q both have three components each, i^, j^ and k^. These can be added along the same.

Thus,  

P+Q    = (2i^+3j^-k^) + (2i^-5j^+ 2k^)

= (2+2)i^ + (3-5)j^ + (-1+2)k^

= 4i^ -2j^ +1k^
