Question

Write image as a complex number. Question 6 options: A) 3 + i B) 3 – i C) –3 + i D) –3 – i

Answer 1

`\\ \rm\Rrightarrow (12-√(-48))/(4)`

`\\ \rm\Rrightarrow (12)/(4)-(√(48)i)/(4)`

`\\ \rm\Rrightarrow 3-4√(3)i/4`

`\\ \rm\Rrightarrow 3-√(3)i`

Answer 2

that's right B) 3 - √3i

Explanation:

(12 - √-48) / 4 =

12/4 - √-48 /4

= 3 - √(-48/16)

= 3 - √-3

= 3 - √ 3i
