Answer:

D.) 4

You are correct :D

Step-by-step explanation:

u = (1 + i[tex]\sqrt{3}[/tex])

v = (1 - i[tex]\sqrt{3}[/tex])

uv = (1 + i[tex]\sqrt{3}[/tex])(1 - i[tex]\sqrt{3}[/tex])

uv = 1 - i[tex]\sqrt{3}[/tex] + i[tex]\sqrt{3}[/tex] - (i[tex]\sqrt{3}[/tex])^2

note that i^2 is equal to -1.

The middle also cancels each other out.

If you squared anything that is under a square root, you just drop the square root.

uv = 1 - (-1)*3

uv = 1 + 3

uv = 4
