Question

Which expression demonstrates the use of the commutative property of addition in the first step of simplifying the expression (–3 + i) + (18 + 5i)?

Answer 1

Answer:
`(-3+18)+(i+5i)`

Explanation:

The commutative property of addition states that the order in which numbers are added does not change the sum. In the context of complex numbers, this means that you can rearrange the real and imaginary parts separately.

So, the expression that demonstrates the use of the commutative property of addition in the first step of simplifying the expression
`(-3+i)+(18+5i)`

would be:


`(-3+18)+(i+5i)`
