Web3 √x^2= x , What about √-x^2 ? If we use the number 5 as en example, would this evaluate to √-5^2 = √25 =5 OR do we need to get the imaginary number 'i' involved, resulting in √-5^2 = 5i I have found many conflicting answers Any clarification on the topic would be much appreciated Kind Regards square-numbers Share Cite Follow WebTo find the radical expression end point, substitute the x x value 0 0, which is the least value in the domain, into f (x) = √x f ( x) = x.
