Question

Evaluate by De Moivre’s Theorem and express the result in rectangular form.

\left\{ 3\left( \frac{ sqrt{2} }{ 2 } -j \frac{ sqrt{2} }{ 2 }\right)^{\frac{ 1 }{ 3 }} \right\}^{\frac{ 1 }{ 2 }}

Answer 1

\[\left\{ 3\left( \frac{ \sqrt{2} }{ 2 } -j \frac{ \sqrt{2} }{ 2 }\right)^{\frac{ 1 }{ 3 }} \right\}^{\frac{ 1 }{ 2 }}\]

Answer 2

Oh, you're here? lol
a good step would be to convert that complex number to polar form ^.^

Answer 3

ahh okay thanks a lot.. I'll try it
