Question

What is 4 + 3i^2 and is it real or imaginary?

Answer 1

Real

$\\ \sf\longmapsto 4+3i^2$

• i^2=-1

$\\ \sf\longmapsto 4+3(-1)$

$\\ \sf\longmapsto 4-3$

$\\ \sf\longmapsto 1$

Answer 2

Answer:

4+6i

Step-by-step explanation:

Distribute the 2 to the 3i

You get 6i, you can't add 4 to 6i because 4 is real and 6i is imaginary.

It's a complex imaginary number
