Sqrt Group TitleBest ResponseYou've already chosen the best response.0
The number is not necessarily positive, but the definition is the value by which the number is farthest from zero (distance). Eg 1 and 1 both are 1 unit away from zero. That is why it is represented as a positive number. Also, distance can't be represented as a negative number. (e.g. You can't be 5 km away from home.)

Since √3i does not represent distance, the solution should only be written as x ≤ √5

Sqrt Group TitleBest ResponseYou've already chosen the best response.0
"There is actually no such thing as a plusorminus square root: it is merely language used to save words. For example, the equation x²=9 has two solutions, which are x=3 and x=3. It is tedious to say: “since x²=9, x must be 3 or 3″. As a shortcut, we say: “since x²=9, x must be ±3.” http://www.xamuel.com/plusorminussquareroots/
