Question

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

Answer 1

4+6i

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

Answer 2

Real

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

• i^2=-1

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

`\\ \sf\longmapsto 4-3`

`\\ \sf\longmapsto 1`
