Penjelasan dengan langkah-langkah:

$1) \ a) sqrt[3]{27} = sqrt[3]{ {3}^{3} } = 3 \ b) {2}^{ frac{5}{3} } = {2}^{1 frac{2}{3} } = {2}^{1} sqrt[3]{ {2}^{2} } = 2 sqrt[3]{4}$

$2) \ a) sqrt[3]{ {5}^{2} } = {5}^{ frac{2}{3} } \ b) sqrt[5]{81} = sqrt[5]{ {3}^{4} } = {3}^{ frac{4}{5} }$

$3) \ {4}^{ frac{5}{2} } div {4}^{ frac{5}{4} } = {4}^{ frac{5}{2} - frac{5}{4} } = {4}^{ frac{10 - 5}{4} } = {4}^{ frac{5}{4} } \ = {2}^{2 times frac{5}{4} } = {2}^{ frac{5}{2} } = {2}^{2 frac{1}{2} } = 4 sqrt{2}$
