Answer 1

$sqrt[3]{ sqrt[3]{81 {t}^{12} } } = sqrt[9]{ {3}^{4} } sqrt[3]{t^{4} } = sqrt[9]{81} sqrt[3]{ {t}^{4} }$
$frac{ sqrt[4]{32} }{ 6 sqrt[4]{2} } = frac{sqrt[4]{16} }{6} = frac{2}{6} = frac{1}{3}$
$sqrt[3]{54 times 32} - sqrt{8 times 162} = \ = sqrt[3]{2 times {3}^{3} times {3}^{5} } - sqrt{ {2}^{3} times 2 times {3}^{4} } = \ sqrt[3]{2 times 3 ^{2} times {3}^{6} } - sqrt{ {2}^{4} times {3}^{4} } = \ = {3}^{2} sqrt[3]{18} - 4 times 9 = \ = 9 sqrt[3]{18} - 36$
