\(x^{\frac{-3}{4}}.x^{\frac{3}{5}}\)
\(x^{\frac{-3}{4}}.x^{\frac{3}{5}}\\= x^{ \frac{-3}{4} + \frac{3}{5} }= x^{\frac{-3}{20}}\\=\frac{1}{\sqrt[20]{ x^{3} }}=\frac{1}{\sqrt[20]{ x^{3} }}.
\color{purple}{\frac{\sqrt[20]{ x^{17} }}{\sqrt[20]{ x^{17} }}} \\=\frac{\sqrt[20]{ x^{17} }}{|x|}\\---------------\)
