Please help if you’re good at math!! algebra 2!!

Answer 1

D.) 4

You are correct :D

Explanation:

u = (1 + i
`√(3)`)

v = (1 - i
`√(3)`)

uv = (1 + i
`√(3)`)(1 - i
`√(3)`)

uv = 1 - i
`√(3)` + i
`√(3)` - (i
`√(3)`)^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
