I am having trouble with the following question

If A and B are positive integers and $A^2 + B^2 = 36$ Then what is $A$? The choices are 6, 7, 8, 9, or 10.

How does one show that answer is 10?

    Surely by mistake. You seem to be having a run of mistakes in your sources.2012-07-11

    Is it $36$ or $136$?2012-07-11

    A^2 - B^2 =36 so A=10 , B=8 OR Marvis's comment2012-07-11

    The answer to the problem as written is not $10$. The only possibility is $36=6^2+0^2$.2012-07-11
