Surd of root 80
Weba, b < 0. If 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 are both positive real numbers. WebDec 10, 2024 · Definition of surd. Any root of a number which can not be exactly found is called a surd. Let a be a rational number and n is a positive integer.
