The Answer of Write $$z _ { 1 } = 2 i$$ and $$z _ { 2 } = - 2 + 2 i$$ in polar form, and then find $$z _ { 1 } z _ { 2 }$$ , $$z _ { 1 } / z _ { 2 }$$ , and $$1 / z _ { 1 }$$ .

Write z1=2iz _ { 1 } = 2 iz1​=2i And z2=−2+2iz _ { 2 } = - 2 + 2 iz2​=−2+2i

Write $z _ { 1 } = 2 i$ And $z _ { 2 } = - 2 + 2 i$
