n^2 because 2n is the same as n+n, but n^2 is the same as the product of n and n

Answer:
n^(2)

Explanation:

(n + n) represents the definition of the sum of n and itself.

(2n) means two times n, wich is the same as adding n + n.


n^(2) actually represents the multiplication of n two times:
n*n

For example, if n=3:


n+n=3+3=6


2n=2(3)=6


n^(2)=3^(2) =9
