Take index = 2. Does this mean the radicand is a square of some number? If yes, is there any number whose square is a negative number? If not, can the radicand be negative?

    If the radicand is a negitive number disregard the - sign and automaticaly pull an i out of the equation indicating that the number is now in the imaginary number system
