$$x=9i\sqrt{-\frac{3\times 5^{\log_{2}\left(3\right)}}{\pi +9e}}\approx -10.62235967\text{, }y=3i\sqrt{-\frac{3\times 5^{\log_{2}\left(3\right)}}{\pi +9e}}\approx -3.540786557$$

$$x=-9i\sqrt{-\frac{3\times 5^{\log_{2}\left(3\right)}}{\pi +9e}}\approx 10.62235967\text{, }y=-3i\sqrt{-\frac{3\times 5^{\log_{2}\left(3\right)}}{\pi +9e}}\approx 3.540786557\text{, }\sqrt{-3\times 5^{\log_{2}\left(3\right)}}\neq 0$$

Datrys ar gyfer x, y

$$x=9\times 5^{\frac{\log_{2}\left(3\right)}{2}}\sqrt{\frac{3}{\pi +9e}}\approx 10.62235967$$

$$y=3\times 5^{\frac{\log_{2}\left(3\right)}{2}}\sqrt{\frac{3}{\pi +9e}}\approx 3.540786557$$
