Express your answer in the form (a + bi)

(21 + 2i) + (13 + 8i) =

The answer to your question is   (34 + 10i)

Step-by-step explanation:

Data

            (21 + 2i) + (13 + 8i) =

To solve this operation, just sum up the whole numbers and get a result then, sum up the imaginary numbers and get another result. Finally, write the result.

-Whole numbers            21 + 13 = 34

-Imaginary numbers       2i + 8i = 10i

Result                               (34 + 10i)

34 +10i

Step-by-step explanation:

( 21 + 2i) + (13 + 8i) =

Add the real numbers

21+13 = 34

Add the imaginary numbers

2i+8i = 10i

The complex number is the real plus the imaginary number

34 +10i
