For some of these all you need to do is apply the definitions.

So what would this be?

This isn't an equation, it's an expression. For this to be an equation there needs to be an equal sign. Is it supposed to bex^2 + 1 - (square root of 3i)

find all solutions, imaginary too.

Convert the number 1 to the polar form for a complex number.[/quote]Find solutions for 5th root of 1

where

Thus r = 1 and . However, note that we can always multiply by a where n is an integer. So

Now put n = 0, 1, 2, 3, and 4.

Polar coordinates of (square root of 2), (square root of -2)

and

So we know that

So

Again
