Is there a term for the fact that a number can be expressed in many ways, e.g., 3 can be written as (3/1)^1 and mean the same thing? Or the fact that the value of a number such as 3 can be expressed in infinite ways and still retain the same value? For instance, the value of 3 can be expressed as (2^2  1) or (3x3 +3)/4? Is there a formal term for these sorts of things? A morphism of some kind? Is there a formal way to express the infinite ways a single value can be expressed?

I guess they could be called "equivalent expressions".

30=3, 41=3, 52=3, 63=3, .........., n(n3)=3 Seems kinda useless stuff...why are you asking?
