    thank you

    Sorry, completely misread the order of the letters. No, b is correct. Because 13/0 is undefined.

    ohhhhh

    thank you!

    The square root of 1/16 is 0.25 which is a real number. When the number under the square root is negative , that's when you have a number that is not real.
