Question

помогите пожалуйста

Answer 1

$frac{4* sqrt[6]{4 sqrt{2} } }{ sqrt[4]{8 sqrt[3]{4} } } = frac{ 2^{2}* sqrt[6]{2^{2}* 2^{1/2} } }{ sqrt[4]{2^{3}*2^{2/3}} } = frac{2^{2}*2^{1/4}}{2^{11/12}} = frac{2^{9/4}}{2^{11/12}} =2^{9/4-11/12}=2^{4/3} =sqrt[3]{2^{4}}= \ =2 sqrt[3]{2}$
$sqrt[4]{256 a^{4}* b^{8}* c^{12} } =4|a|* b^{2}*c^{3} =-4a* b^{2}*c^{3}$
