  1. I interpret
    "adding the square root of 16 and -8"
    as
    "adding the square root of 16 and the square root of -8"
    which gives
    sqrt(16)+sqrt(-8)
    = 4+2√2 i
    which is a complex irrational number.

    If I interpret
    "adding the square root of 16 and -8"
    as
    "the square root of the sum of 16 and -8", then
    the result is
    √(16-8)=√8=2√2
    which is an irrational number.

    You may be in a better position to judge what your teacher means.
