Question

помогите пожалуйста!!!!

Answer 1

$\sqrt[3]{ {5}^{3} \times {7}^{3} } = 5 \times 7 = 35$

$\frac{ \sqrt[3]{2} \times \sqrt[3]{4} }{ \sqrt[4]{81} } = \frac{ \sqrt[3]{2 {}^{3} } }{ \sqrt[4]{ {3}^{4} } } = \frac{2}{3}$

$\frac{(0. 3 ) {}^{0.3} \times (0.3) {}^{ - 1} }{(0.3 ){}^{1.3} } = (0.3) {}^{0.3 - 1 - 1.3 } =( 0.3 ){}^{ - 2} = \\ ( \frac{3}{10} ) {}^{ - 2} = ( \frac{10}{3} ) {}^{2} = \frac{100}{9} = 11 \frac{1}{9}$
