Løs y=7/(x^3-x^2+7x)^5

$$y = \frac { 7 } { ( x ^ { 3 } - x ^ { 2 } + 7 x ) ^ { 5 } }$$

Løs for x

$$x=\frac{2^{\frac{2}{3}}\left(\sqrt[3]{-61\sqrt[5]{y|y|}+3\sqrt[5]{y}\sqrt{3\left(1323y^{\frac{2}{5}}-122\sqrt[5]{7y}+27\times 7^{\frac{2}{5}}\right)}+27\sqrt[5]{7|y|}}+\sqrt[3]{-61\sqrt[5]{y|y|}-3\sqrt[5]{y}\sqrt{3\left(1323y^{\frac{2}{5}}-122\sqrt[5]{7y}+27\times 7^{\frac{2}{5}}\right)}+27\sqrt[5]{7|y|}}+\sqrt[3]{2}\sqrt[15]{y|y|}\right)}{6\sqrt[15]{y|y|}}$$

$$y\neq 0$$

Løs for y

$$y=\frac{7}{\left(x\left(x^{2}-x+7\right)\right)^{5}}$$

$$x\neq 0$$
