Ответ:

1)

$( \sqrt[8]{18}) {}^{8} = 18 {}^{ \frac{8}{8} } = 18 {}^{1} = 18$

2)

$( - \sqrt[9]{9} ) {}^{9} = ( - 9) {}^{ \frac{9}{9} } = \\ = ( - 9) {}^{1} = - 9$

3)

$( - \sqrt[6]{11} ) {}^{6} = 11 {}^{ \frac{6}{6} } = 11 {}^{1} = \\ = 11$

4)

$( \frac{1}{3} \sqrt[3]{45} ) {}^{3} = \frac{1 {}^{3} }{3 {}^{3} } \times ( \sqrt[3]{45} ) {}^{3} = \\ = \frac{1}{27} \times 45 {}^{ \frac{3}{3} } = \\ = \frac{1}{27} \times 45 {}^{1} = \\ = \frac{1}{27} \times 45 = \\ = \frac{45}{27} = \frac{9 \times 5}{9 \times 3} = \frac{5}{3}$
