Given information:

A relation is given as

  2(3+5)=(3+5)2

Calculation:

Commutative property over addition of real numbers:

If two real numbers are multiplied then the result does not depend on the order of multiplication.

Suppose a and b are two real numbers, commutative property says that

  c(a+b)=(a+b)c

Therefore, in 2(3+5)=(3+5)2 , Commutative property over multiplicationof real numbers has been used.
