Can a radical be negative? - Answers

In mathematics, a radical typically refers to the root of a number, such as the square root. The value under a radical can be negative, but if we're talking about real numbers, the square root of a negative number is not defined in the real number system; instead, it results in an imaginary number. However, if you're considering other radicals, like cube roots, the radical itself can yield a negative result if the number under the radical is negative.
