From the concept, can you guess that "the square of 997" and "997 squared" are identical? In this, 997 would only be one side of a square, the root. Webster's New International Dictionary Unabridged, for "square" (noun) definition 4 is "the product of a number or quantity multiplied by itself" -- FYI.
