Which of the following correctly simplifies the expression −17+5+3i−8 and expresses it in the form of a+bi ?

1 answer

To simplify the expression 17+5+3i8, we will combine the real parts and the imaginary parts separately.

  1. Combine the real numbers: 17+58=17+5=12then128=20

  2. The imaginary part remains as: 3i

Now, putting it all together, we have: 20+3i

Thus, the expression in the form a+bi is: 20+3i
