## anonymous one year ago How would I solve these questions? Find complex roots in polar form 1)the fourth roots of 4-4sqrt3i 2)cube roots of -1-i

1) we have formula for this fourth root of z means $$\sqrt[4]z$$ , right?

2. Loser66

it is $$z^{1/4}$$ , right?

3. anonymous

yes i think so

4. Loser66

so, if you set $$z= 4-4i\sqrt3$$

5. Loser66

6. Loser66

hence in polar form, you have z =???

sorry im still new to this concept. im a little confused about how we split the equation to find x and y
