Подробное решение
Дано уравнение
$$x^{8} = -36$$
Т.к. степень в ур-нии равна = 8 и свободный член = -36 < 0,
зн. действительных решений у соотв. ур-ния не существует
Остальные 8 корня(ей) являются комплексными.
сделаем замену:
$$z = x$$
тогда ур-ние будет таким:
$$z^{8} = -36$$
Любое комплексное число можно представить так:
$$z = r e^{i p}$$
подставляем в уравнение
$$r^{8} e^{8 i p} = -36$$
где
$$r = \sqrt[4]{6}$$
- модуль комплексного числа
Подставляем r:
$$e^{8 i p} = -1$$
Используя формулу Эйлера, найдём корни для p
$$i \sin{\left(8 p \right)} + \cos{\left(8 p \right)} = -1$$
значит
$$\cos{\left(8 p \right)} = -1$$
и
$$\sin{\left(8 p \right)} = 0$$
тогда
$$p = \frac{\pi N}{4} + \frac{\pi}{8}$$
где N=0,1,2,3,...
Перебирая значения N и подставив p в формулу для z
Значит, решением будет для z:
$$z_{1} = - \sqrt[4]{6} \sqrt{\frac{1}{2} - \frac{\sqrt{2}}{4}} + \sqrt[4]{6} i \sqrt{\frac{\sqrt{2}}{4} + \frac{1}{2}}$$
$$z_{2} = \sqrt[4]{6} \sqrt{\frac{1}{2} - \frac{\sqrt{2}}{4}} - \sqrt[4]{6} i \sqrt{\frac{\sqrt{2}}{4} + \frac{1}{2}}$$
$$z_{3} = - \sqrt[4]{6} \sqrt{\frac{\sqrt{2}}{4} + \frac{1}{2}} - \sqrt[4]{6} i \sqrt{\frac{1}{2} - \frac{\sqrt{2}}{4}}$$
$$z_{4} = \sqrt[4]{6} \sqrt{\frac{\sqrt{2}}{4} + \frac{1}{2}} + \sqrt[4]{6} i \sqrt{\frac{1}{2} - \frac{\sqrt{2}}{4}}$$
$$z_{5} = - \frac{2^{\frac{3}{4}} \cdot \sqrt[4]{3} \sqrt{\frac{1}{2} - \frac{\sqrt{2}}{4}}}{2} + \frac{2^{\frac{3}{4}} \cdot \sqrt[4]{3} \sqrt{\frac{\sqrt{2}}{4} + \frac{1}{2}}}{2} + \frac{2^{\frac{3}{4}} \cdot \sqrt[4]{3} i \sqrt{\frac{1}{2} - \frac{\sqrt{2}}{4}}}{2} + \frac{2^{\frac{3}{4}} \cdot \sqrt[4]{3} i \sqrt{\frac{\sqrt{2}}{4} + \frac{1}{2}}}{2}$$
$$z_{6} = \frac{2^{\frac{3}{4}} \cdot \sqrt[4]{3} \sqrt{\frac{1}{2} - \frac{\sqrt{2}}{4}}}{2} + \frac{2^{\frac{3}{4}} \cdot \sqrt[4]{3} \sqrt{\frac{\sqrt{2}}{4} + \frac{1}{2}}}{2} - \frac{2^{\frac{3}{4}} \cdot \sqrt[4]{3} i \sqrt{\frac{\sqrt{2}}{4} + \frac{1}{2}}}{2} + \frac{2^{\frac{3}{4}} \cdot \sqrt[4]{3} i \sqrt{\frac{1}{2} - \frac{\sqrt{2}}{4}}}{2}$$
$$z_{7} = - \frac{2^{\frac{3}{4}} \cdot \sqrt[4]{3} \sqrt{\frac{\sqrt{2}}{4} + \frac{1}{2}}}{2} - \frac{2^{\frac{3}{4}} \cdot \sqrt[4]{3} \sqrt{\frac{1}{2} - \frac{\sqrt{2}}{4}}}{2} - \frac{2^{\frac{3}{4}} \cdot \sqrt[4]{3} i \sqrt{\frac{1}{2} - \frac{\sqrt{2}}{4}}}{2} + \frac{2^{\frac{3}{4}} \cdot \sqrt[4]{3} i \sqrt{\frac{\sqrt{2}}{4} + \frac{1}{2}}}{2}$$

делаем обратную замену
$$z = x$$
$$x = z$$
Тогда, окончательный ответ:
