Share Improve this answer Follow WebThis is often overlooked in favor of considering only the principal root (smallest argument greater than or equal to zero) as is the case with the square root (which will result in real numbers only in the case that x is a non-negative real number). In the further case that y is an irrational number, then there are infinitely many solutions.

WebSquare roots of negative numbers are not real numbers, and they do not satisfy all the properties of square roots of positive numbers. However, the radical form √x is used when x < 0. When x is negative, √x = i √– x. For example, √√–7 = i 7 . Other even roots of negative numbers (4th roots, 6th roots, 8th roots, and so on) are WebAnd here, there simply is no square root of a negative number simply because a square is always non-negative. So, the expression is not defined within the real numbers, hence cannot be calculated. Additionally, "solved" should be rather used in the case of equalities or inequalities. An expression is "evaluated" or "calculated". Add a comment
