    Rational for most people's needs.

    Complex once you get below the surface.

    I is an imaginary number, not a real number, therefore, it cannot be classified as rational or irrational.

    neither because rational and irrational apply only to real numbers

    It is not only not rational, it is not real.

    NEITHER. The number i belongs to the Complex Number System.

    Irrational. A lower case "i" is uses for the square root of -1. If you use "I," no one else knows what you are talking about.

    The rational and irrational numbers are subsets of the real numbers. The imaginary number i is not a real number and is therefore neither rational not irrational.

    Your question is similar to asking if 0.5 is even or odd. Even and odd parity only apply to the integers so it wouldn't make sense to ask if a non-integer was even or odd.

    Answer:

    Neither

  • Can i be expressed as the ratio of 2 integers?  If yes, then it is rational.  If not, then it is irrational.
