Answer 1

1.

$sqrt[3]{13}$≈2.35133

$sqrt[6]{45}$≈1.88597

$sqrt{2}$≈1.41421

$sqrt[12]{231}$≈1.57387

В порядке возрастания:

$sqrt{2}$; $sqrt[12]{231}$; $sqrt[6]{45}$; $sqrt[3]{13}$

а) $sqrt[4]{0.0625} +  sqrt[5]{-243} = sqrt[4]{frac{1}{16} } - 3 = frac{1}{2} -3 = - frac{5}{2}$

б) $sqrt[4]{2^{5}*3^{2}} *  sqrt[4]{2^{11}*3^{9}} = sqrt[4]{2^{5}*3^{2}*2^{11}*3^{9}}= sqrt[4]{2^{16}*3^{11}}  =  sqrt[4]{2^{5}*6^{11}} = sqrt[4]{32*6^{11}} = 2 * 6^{2}* sqrt[4]{2*6^{3}} = 72sqrt[4]{2*6^{3}} = 72sqrt[4]{432} = 144 sqrt[4]{27}$

г) $frac{sqrt[4]{32} }{sqrt[4]{8} sqrt[4]{64} }  = frac{sqrt[4]{32} }{sqrt[4]{512} } = frac{1}{2}$

д) $sqrt[6]{5^{5}*3^{4}} *  sqrt[12]{5^{2}*3^{4}} = sqrt[12]{(5 * 15^{4})^{2}*5^{2}* 3^{4}}=sqrt[12]{81*625*15^{8}} =sqrt[12]{50625*15^{8}} = sqrt[12]{15^{4}*15^{8}}=sqrt[12]{15^{12}}=15$

3.$frac{47*sqrt[7]{sqrt[18]{a}} - 7 sqrt[3]{sqrt[42]{a}} }{18*sqrt[6]{sqrt[21]{a}}} = frac{47*sqrt[126]{a} - 7 sqrt[126]{a} }{18 *sqrt[126]{a}}=frac{40sqrt[126]{a}} {18sqrt[126]{a}} = frac{20}{9}$

4.$frac{(6frac{2}{3}+2frac{4}{15}+5frac{1}{2})/frac{1}{15}-30/frac{5}{28}} {(5frac{4}{5}-0.6xfrac{5}{22})*48frac{1}{2}} = frac{(4+frac{8}{15}+frac{5}{2})*15-6*28}{(4-3frac{1}{22})*24} = frac{frac{211}{30}*15-168}{(4-frac{3}{22})*24}= - frac{frac{125}{2}} {}frac{1020}{11} = - frac{275}{408}$
