Here I was patting myself on the back, never count your chickens until you hatch the square roots. Now I am once again reminded that in the dark mysterious world of square roots reside some very nasty bed fellows in this case the unlucky 7!

I see this is the second time at this rodeo. I still get many of last years ones wrong but this time I used backsolved and quickly discovered without wasting time on FOILing that the 4 was only going to work. Thanks to the first chapter on backsolve PWN I did not waste time here. Half the battle in the time game is to pick the correct and fastest approach to get correct answers
