Resol sqrt{u^5}=3

$$\sqrt { u ^ { 5 } } = 3$$

Resoleu u (complex solution)

$$u=3^{\frac{2}{5}}e^{\frac{2\pi i}{5}}\approx 0,479546655+1,475892845i$$

$$u=3^{\frac{2}{5}}\approx 1,551845574$$

$$u=3^{\frac{2}{5}}e^{\frac{4\pi i}{5}}\approx -1,255469442+0,912151942i$$

$$u=3^{\frac{2}{5}}e^{\frac{6\pi i}{5}}\approx -1,255469442-0,912151942i$$

$$u=3^{\frac{2}{5}}e^{\frac{8\pi i}{5}}\approx 0,479546655-1,475892845i$$

Resoleu u

$$u=3^{\frac{2}{5}}\approx 1,551845574$$
