Ch 11 Review

Can anyone help me with these problems?( 14c,d,e)

When I did c ( six roots of root 3 + i), I ended up with r = 2^(1/6) & 6T= pi/6 + 2pi i

I missed the example during class for finding what -3 + 2i is a cube root of..

For e,  is root 2 ^(3) the same as 6 root 2?

chapter 11 review

i was wondering if anyone could help me with two questions on the review...

for #13 letter c. i'm not getting (2-root2)cis(5pi/12)

i keep getting just (root2)cis(5pi/12)

also for #16 letter b. i'm not sure how to get [(x^2+y^2-2x)]^2

if anyone has any idea if they could let me know, thanks.
