Answer 1

$sqrt[18]{a^3} = sqrt[18:3]{a^{3:3}} = sqrt[6]{a} \ sqrt[3]{m^2 sqrt[4]{m} } = sqrt[3]{ sqrt[4]{(m^2)^4} sqrt[4]{m} } =sqrt[3]{ sqrt[4]{m^{2cdot4+1}} } =sqrt[3cdot4]{m^{9} } =sqrt[3cdot4]{m^{3cdot3} } =sqrt[4]{m^{3} } \ sqrt[8]{a^8} =|a|=a (a geq 0) \ sqrt[4]{(a-1)^4} =|a-1|=1-a (a leq 1)$
