Let us suppose I have a number ##x## such that ##x<0##. If I want to write the roots of the ##x^{1/n}##. How can we write the roots of this number. I thought we can write
$$|x|^{1/n}e^{i\pi\theta}$$ for ##\theta = \frac{2l + 1}{n}## and ##l = 0,1,2## etc.
Is this correct ?
Similary If I wanted to write ##x^{m/n}##, I should I write
$$|x|^{m/n}e^{mi\pi\theta}$$ for ##\theta = \frac{2l + 1}{n}## ?
$$|x|^{1/n}e^{i\pi\theta}$$ for ##\theta = \frac{2l + 1}{n}## and ##l = 0,1,2## etc.
