# How do you perform the operation and write the result in standard form given (1.6+3.2i)+(-5.8+4.3i)?

$- 4.2 + 7.5 i$

#### Explanation:

We have: $\left(1.6 + 3.2 i\right) + \left(- 5.8 + 4.3 i\right)$

Let's group the real and imaginary parts of these complex numbers, respectively:

$= \left(1.6 - 5.8\right) + \left(3.2 + 4.3\right) i$

$= - 4.2 + 7.5 i$
