which property of addition is shown below?\na + bi + c + di = a + c + bi + di\nidentity property\nassociative…

Brief Explanations:

The commutative property of addition states that for any two numbers (m) and (n), (m + n=n + m). In the given expression (a + bi + c+di=a + c+bi + di), the terms (c) and (bi) have been swapped, which is characteristic of the commutative property. The identity property involves adding 0, the associative property involves grouping of terms ((m + n)+p=m+(n + p)), and the inverse property involves adding the additive - inverse to get 0.

Answer:
