Passos de solució

Simplifiqueu 2.

$$2\left(\frac{\sqrt[3]{3x+y}}{\sqrt{x-2y}}-\frac{2\left(3x+y\right)}{\left(x-2y\right)^{\frac{5}{2}}}\right)$$

Considereu \left(x-2y\right)^{-\frac{1}{2}}\sqrt[3]{3x+y}-2\left(x-2y\right)^{-\frac{5}{2}}\left(3x+y\right). Simplifiqueu \frac{\sqrt[3]{3x+y}}{\sqrt{x-2y}}.

$$\frac{\sqrt[3]{3x+y}\left(1-\frac{2\left(3x+y\right)^{\frac{2}{3}}}{\left(x-2y\right)^{2}}\right)}{\sqrt{x-2y}}$$
