    RE:

    1) For some reason the system indicates that there is more than one answer. Do you see any more answers?

    2) I knew it was Pyth. Theorem so I wrote a^2+b^2 and the system counted it wrong.

    1. Since the system catches 1%, you should write everything that in the range 7.29109 1% = 7.29109 0.0729109 = [7.21818 , 7.364].
    You should thus add the third and last choice.
    2. Maybe it is a "vector space" and the system wants to hear a+b and not the magnitude a^2+b^2. However, the way it is asked I agree your answer is right.
