Well if you knew the answer why did you ask the question, Anthony?

I can exclude certain answers as obviously wrong without necessarily
knowing the correct answer.

For example, while I do not know the square root of ten to fifteen
decimal places off the top of my head, I do know that it is not four.


Wrong answer. The square root of 10 to 15 exactly 4.

The simple proof is left as an exercise for MX.




Ooops. Fixing a typo.

The square root of 10 is exactly 4.
The very simple proof is left to MX.
