Question

3 plus root under 3 is equal to

Answer 1

Answer:

Did you mean √3 - √3?

Or did you mean root(3) - root(3) where root() denotes the two-valued square root function? If you meant that, there are four possible answers:

+√3-(+√3) = 0

+√3-(-√3) = 2√3

-√3-(-√3) = 0

-√3-(+√3) = -2√3

As you can see, two of those answers are numerically the same, but the selection of the value of the root() function was different.
