# How do you write 81^(3/4) in radical form?

${81}^{\frac{3}{4}} \textcolor{w h i t e}{\text{x") underline("in radical form}} = \sqrt[4]{{81}^{3}}$
Note that ${81}^{\frac{3}{4}}$ does not need to be expressed as a radical; it exists as a simple integer:
${81}^{\frac{3}{4}} = {\left(\sqrt[4]{81}\right)}^{3} = {3}^{3} = 27$
