Oi. Foram simplificadas :)
![\sqrt[4]{3} \sqrt[4]{27} = \sqrt[4]{81} = \sqrt[4]{3^4}= 3^{ \frac{4}{4} } =3^1= 3](https://tex.z-dn.net/?f=+%5Csqrt%5B4%5D%7B3%7D++%5Csqrt%5B4%5D%7B27%7D+%3D+%5Csqrt%5B4%5D%7B81%7D+++%3D+%5Csqrt%5B4%5D%7B3%5E4%7D%3D+3%5E%7B+%5Cfrac%7B4%7D%7B4%7D+%7D+%3D3%5E1%3D+3 "\sqrt[4]{3} \sqrt[4]{27} = \sqrt[4]{81} = \sqrt[4]{3^4}= 3^{ \frac{4}{4} } =3^1= 3")
