Solve y=m^4,(3y-8)(3y-2)=0

$$y = m ^ { 4 } , ( 3 y - 8 ) ( 3 y - 2 ) = 0$$

Solve for y, m (complex solution)

$$y=\frac{8}{3}\approx 2.666666667\text{, }m=\frac{6^{\frac{3}{4}}}{3}\approx 1.277886208$$

$$y=\frac{8}{3}\approx 2.666666667\text{, }m=\frac{6^{\frac{3}{4}}i}{3}\approx 1.277886208i$$

$$y=\frac{8}{3}\approx 2.666666667\text{, }m=-\frac{6^{\frac{3}{4}}}{3}\approx -1.277886208$$

$$y=\frac{8}{3}\approx 2.666666667\text{, }m=-\frac{6^{\frac{3}{4}}i}{3}\approx -0-1.277886208i$$

$$y=\frac{2}{3}\approx 0.666666667\text{, }m=\frac{3^{\frac{3}{4}}\sqrt[4]{2}}{3}\approx 0.903602004$$

$$y=\frac{2}{3}\approx 0.666666667\text{, }m=\frac{3^{\frac{3}{4}}\sqrt[4]{2}i}{3}\approx 0.903602004i$$

$$y=\frac{2}{3}\approx 0.666666667\text{, }m=-\frac{3^{\frac{3}{4}}\sqrt[4]{2}}{3}\approx -0.903602004$$

$$y=\frac{2}{3}\approx 0.666666667\text{, }m=-\frac{3^{\frac{3}{4}}\sqrt[4]{2}i}{3}\approx -0-0.903602004i$$
