Поможешь? Спасибо большое...)

Answer 1

$2)\frac{21^{12} }{(7^{4} )^{3}*(3^{2})^{4}}=\frac{7^{12}*3^{12}}{7^{12}*3^{8}}=3^{12-8}=3^{4}=81\\\\Otvet:\boxed{81}$

$3)(\frac{3}{2})^{6}*(\frac{2}{3})^{5}=\frac{3^{6}*2^{5}}{2^{6}*3^{5}} =\frac{3}{2}=1,5\\\\125^{o}=1\\\\1,5>1\Rightarrow(\frac{3}{2})^{6}*(\frac{2}{5})^{5}>125^{o}$
