ok im gonna supply some preps I got from exam(all that i remember) and I want you to estimate the degree of roughness

Find the square roots

1) |z|^{9}+27=0

2)find homogenus system

x+y-c+2z=0

-x+2y+c+z=0

x+y+c+z=0

2x+y+c+2z=0 ------->im not sure but its pretty similar I think the concept could be the same

3)vector A(2,3,1) B(3,2,2) C(1,2,1) find vector D

I DONT WANT YOU TO SOLVE MY EQUATION BUT JUST GIVE OUT THOUGHTS of a possible solution BTW I failed this exam, next one I'll be hoping to get in is in june

2. Relevant equations

3. The attempt at a solution
