Question

If u = 1 + 3i and v = -2 − i, what is u + v?

Answer 1

Explanation:

you need to replace definition of both u and v into the equation

u + v = (1+3i) + (-2-i)

= 1 + 3i -2 - i

= 3i - i + 1 - 2

= 2i - 1

Answer 2

2i - 1

Explanation:

The expression is,

→ u + v

Simplifying the expression,

→ u + v

→ (1 + 3i) + (-2 - i)

→ (3i - i) + (1 - 2)

→ 2i - 1

Hence, the answer is 2i - 1.
