Find
(1) a + b,
(2) 2a + 3b,
(3) |a|, and |a − b|.
a = 5i + j, b = i − 2j

Step-by-step explanation:

this problem is on vector

given the vectors

a = 5i + j, and

b = i − 2j

1. summation of vector a + b

collect like terms

2. 2a + 3b

collecting like terms we have

(3) |a|, and |a − b|.

|a|= |5i+j|
