Answer 1

$\Large\boxed{\begin{array}{l}\underline{\rm Pot\hat encia~de~expoente~racional}\\\huge\boxed{\boxed{\boxed{\boxed{\sf\sqrt[\sf n]{\sf a^m}= a^{\frac{m}{n}}}}}}\end{array}}$

$\Large\boxed{\begin{array}{l}\tt a)~\sf 11^{\frac{1}{2}}=\sqrt{11}\\\tt b)~\sf\bigg(\dfrac{5}{9}\bigg)^{\frac{1}{2}}=\sqrt{\dfrac{5}{9}}\end{array}}$
