Q. (4)+(14−4i)=Express your answer in the form (a+bi).
Identify real and imaginary parts: First, identify the real and imaginary parts of the complex numbers to be added.The first number is 4, which is a real number with an imaginary part of 0. So we can write it as (4+0i).The second number is already given in the form of a complex number: (14−4i).Now, we will add the real parts together and the imaginary parts together.
Write the first number in complex form: Add the real parts: 4 (from the first number) and 14 (from the second number).4+14=18
Write the second number in complex form: Add the imaginary parts: 0i (from the first number) and −4i (from the second number).0i−4i=−4i
Add the real parts: Combine the results of the real and imaginary parts to express the sum in the form (a+bi).The sum is (18)+(−4i), which can be written as (18−4i).
