Express the following in the forma+ib. Give all values and make a polar plot of

the points or the vector vectors that represent your result.

(a) (9i)^(1/2)

is this the answer? =3*(cos pi/2 + i sin pi/2)

=3i

so how do we represent this on polar plot?

(b)(-64i)^(1/4)=(64^0.25)*(cos theta/4 + i sin theta/4)

here im getting theta= -pi and +pi so which one do we take?
