Webba, 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. WebbDefinition for negative exponents We define a negative power as the multiplicative inverse of the base raised to the positive opposite of the power: x^ {-n}=\dfrac {1} {x^n} x−n = xn1 Want to learn more about this definition? Check out this video. Examples 3^ {-5}=\dfrac {1} {3^5} 3−5 = 351 \dfrac {1} {2^8}=2^ {-8} 281 = 2−8
