The question is:(adsbygoogle = window.adsbygoogle || []).push({});

If [tex]\sqrt{ABADEC} = BEB[/tex] what is the value of the digit "D"?

I'm completely lost as to how to start on this one. I tried expanding the numbers as powers of ten:

BEB = B*10^{2}+ E*10^{1}+ B*10^{0}

= B(10^{2}+ 1) + 10E

= 101B + 10E

...but I couldn't really do anything with it after that.

I don't want an answer, just a hint on how to proceed.

Thanks!
