# How do you find the power #(1+sqrt3i)^4# and express the result in rectangular form?

One of the most interesting ways in complex numbers is that we can divide and multiply them easily, when we write them in polar form, as compared to the process of multiplication when complex numbers are written in rectangular form.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
