2 answers:
B. Associative Property
, you're working out the numbers in the parentheses before anything else.
Answer:
Properties used here are:
A. Commutative property.
C. Associative property
Step-by-step explanation:
Given the expression:
(7+2i) + (4+3i)
(7+ 2i) + 4 + 3i
According to associative property:
a + (b + c) = (a + b) + c
7 + (2i + 4) + 3i
Using commutative property:
a + b = b + a
7 + (4 + 2i) + 3i
(7 + 4) + (2i + 3i)
Simplify:
11 + 5i
So, we use Commutative & Associative Property.
That's the final answer.
