WebbIf a and b are negative, then the square root of them must be imaginary: ⁺√a = xi ⁺√b = yi x and y must be positive (and of course real), because we are dealing with the principal square roots. ⁺√a • ⁺√b = xi(yi) = -xy-xy must be a negative real number because x and y … WebbTo simplify radicals with negative radicand, one should be familiar with the concept of complex numbers. We use iota (i) to remove the negative sign from the radicand. For example, √-81 can be written as i√81, where the value of iota is √-1.
