Question

Помогите решить, не понимаю

Answer 1

$\sqrt[5]{ - 7 \frac{19}{32} } + \sqrt[4]{0.0001} = \sqrt[5]{ - \frac{243}{32} } + 0.1 = - \frac{3}{2} + 0.1 = - 1.5 + 0.1 = - 1.4 \\ \sqrt[7]{ {2}^{20} \times {5}^{10} } \div \ \sqrt[7]{ {2}^{6} \times {5}^{3} } = \sqrt[7]{ \frac{ {10}^{10} \times {2}^{10} }{ {10}^{3} \times {2}^{3} } } = \sqrt[7]{{10}^{7} \times {2}^{7} } = 10 \times 2 = 20$
