What are the fourth roots of sqrt 3 + i
i mean \[\LARGE \sqrt[4]{\sqrt 3 + i}\]
is that the question?
I don't think so, lol. It's asking for roots in the complex plain. Humiliated yourself again :)
@lgbasallote is right,...:)
it just asks what are the fourth roots of \[\sqrt{3} + i\]
put it in trigonometric form first
Convert \[\sqrt3+i\] Into -> \[|v|(\cos \theta +i \sin \theta)\] or \[|v|cis \]
Once it is converted, use demvoirs thereorm in order to do solve.
I've always found \(\text{cis}(x)\) to be such a lame idea.
\[\sqrt[4]{2cosPi/6+isinPi/6}\]
It's only useful cause you can effectively use demoices therom.
that's the point
Define "effectively"
I have always use deMoivre's theorem without \(\text{cis}(x)\).
Well, go ahead ^_^ @myko z^4=2cos(pi/6)+isin(pi/6) Now use rules of demoivre's theorm.
