complex number sums​

Answer 1

Hey dude here is your Answer------------------------ ✔️✔️

Summary

Use "FOIL" to multiply complex numbers,

Or use the formula: (a+bi)(c+di) = (ac−bd) + (ad+bc)i.

Or use polar form and then multiply the magnitudes and add the angles.

De Moivre's Formula can be used for integer exponents: ...

Polar form r cos θ + i r sin θ is often shortened to r cis θ

Based on the concept of real numbers, a complex number is a number of the form a + bi, where a and b are real numbers and i is an indeterminate satisfying i2 = −1. For example, 2 + 3i is a complex number.....

Hope it helps
