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
