What is the complex number  z=−4√3+4i represented in polar form?

A complex number in the form: z = a + bi  can be written in polar form as: z = r.ei.theta, where r = √(a2 + b2) and theta = tan-1(b/a)  (that's arctan(b/a))

 

You should plug your numbers into these.

 

I notice the polar form sometimes seems to be written as  r.cis(theta)  which is r.cos(theta) + i.r.sin(theta)  (which I think is more like rectangular form!!).
