Verified answer

Объяснение:

[tex] \underbrace{( - \sqrt[6]{17} ) {}^{6} }_{ \geqslant 0}= (\sqrt[ \not6]{17} ) {}^{ \not6} = 17 \\ \\ 3 \cdot \sqrt[3]{ - 4 \frac{17}{27} } = 3 \cdot \sqrt[3]{ - \frac{125}{27} } = - 3 \cdot \sqrt[3]{ \frac{125}{27} } = - 3 \cdot \frac{ \sqrt[3]{125} }{ \sqrt[3]{27} } = - 3 \cdot \frac{ \sqrt[3]{5 {}^{3} } }{ \sqrt[3]{3 {}^{3} } } = - 3 \cdot \frac{5}{3 } = - 1 \cdot5 = - 5[/tex]
