If we write the numbers in power form


\displaystyle \sqrt[3]{5}=5^{{1}/{3}\;} and \displaystyle \sqrt[3]{6}=6^{{1}/{3}\;}


we see that \displaystyle \sqrt[3]{6} is larger since \displaystyle 6 is larger than \displaystyle 5 and both numbers have the same positive exponent, \displaystyle {1}/{3}\;.
