If I have some expression which takes the square root of a square, it
evaluates leaving the whole square root expression unchanged.
Year == (Year^2)^(1/2)
just returns what I entered when evaluated.
Year == Year
evaluates to True.
How do I persuade Mathematica to evaluate the first expression completely?
