Lesson 3.2: Performing Operations with Complex Numbers Answers

Which property allows you to write the expression (3 + 7i) + (8 – 6i) as (8 – 6i) + (3 + 7i)? ✔ commutative associative distributiveidentity

Which property allows you to write the expression [(3 + 7i) + (8 – 6i)] + (1+ 9i) as (8 – 6i) + [(3 + 7i) + (1 + 9i)]? X commutative ✔ associative distributiveidentity

In general, ai + bi =

The sum of 3i + 2i is equal to i.

The associativecommutative✔ distributiveidentity property allows 3i + 2i to be written as (3 + 2)i.

Add (3 − 5i) + (−2 + 8i). Sum of real parts: Sum of imaginary parts: i

3 + i3 – i✔ 1 + 3i–1 – 3i
