Step-by-step explanation:
A+B= (2+4)i + (3-3)j + (1+5)k
= 6i +0j+ 6k
or, A+B = 6i + 6k
Hence,
magnitude of A+B = |A+B|
= √[(6)²+(6)²]
= √36+36
=√2×36
= 6√2 ans.

Given : A=2i+3j+k and B=4i-3j+5k
To find : the magnitude of A+B
Solution
A=2i+3j+k and B=4i-3j+5k
A + B
= (2 + 4)i + (3 - 3)j + (1 + 5)k
= 6i + 0j + 6k
= 6i + 6k
Magnitude of A + B = √6² + 6² =6√2
the magnitude of A+B is =6√2
