LOL, there isn't any!

There are two answers 1 and 64

26, known as Fermat's Sandwich Theorem.

The only number in that list which is not a square number is 27. 27 is a cube number.

The only significant difference that I know of is that there is a method, somewhat like long division, that can be used for finding the square root. I am not aware of a similar process for a cube root.

64EDIT: Someone suggested any even number multiplied by itself, but this is not true as the result would not be a cube number. The only number that satisfies the criteria in the question is 64, because;it has 2 digitsit is a square number (8 x 8 = 64)it is a cube number (4 x 4 x 4 = 64)
