We have to add 3 + 2i + 1 -5i.
When adding complex and real numbers complex terms can be added with each other only. The same goes for the real terms.
So 3 + 2i + 1 -5i
=> 3 + 1 + 2i -5i
=> 4 - 3i
The required result is 4 - 3i.
basically u just add the i's and the normals
To add the complex numbers.
Add the real numbers and add the complex nnumbers.
3+2i+1-5i = (3+1)+(2i-5i).
3+2i+1-5i = 4+(2-5)i.
3+2i+1-5i = 4 -3i.
The complex numbers from this addition are:
z1 = 3+2i and z2 = 1-5i
We'll add the real parts and the imaginary parts:
(3+1) + (-5i+2i)
4 - 3i
The complex number resulted from the addition of the given complex numbers z1 and z2 is:
z = z1 + z2
z = 4 - 3i, where the real part is Re(z) = 4 and the imaginary part is Im(z) = -3.
