Question

помогите пожалуйста!!! задания во вложениях

Answer 1

$22) ...=(7cdot{sqrt{sqrt{216}}}+^{4}sqrt{216})^{4/3}=(7cdot{^{4}sqrt{6^{3}}}+^{4}sqrt{6^{3}})^{4|3}=\ =(8^{4/3}cdot{6^{3/4}})^{4/3}= ^{3}sqrt{8^{4}}cdot{6}=2^{4}cdot{6}=16cdot{6}=96$
23) $...=(127sqrt{2cdot{^{4}sqrt{8}}}+^{4}sqrt{sqrt{4cdot{32}}})^{-8/7}cdot{1024}=\=(127cdot{2^{7/8}}+2^{7/8})^{-8/7}cdot{1024}=\=(128cdot{2^{7/8})^{-8/7}cdot{2^{10}}=(2^{7})^{-8/7}cdot{2^{-1}}cdot{2^{10}}=2$
