Let z = a + bi be the complex form and 2 = r(cos 6+ i sin 8) be the polar form of a complex number. 1) When doing addition and subtraction between two complex numbers, which form is better? In your own language, describe how to add/subtract two complex numbers, 2) When doing multiplication and division between two complex numbers, which form is better? In your own language, describe how to multiply/divide two complex numbers. 3) When we raise a power (integer power) or find the nth root of a complex number, which form is better? In your own language, describe how to raise a power of a complex number and how to take the nth root of a complex number.
