Criteria for Combining Higher-Order Radicals

A metal fabrication technician is simplifying the expression 484+2434\sqrt[4]{48} + \sqrt[4]{243} to calculate the total length of a component. After simplifying the terms to $2\sqrt[4]{3} and $3\sqrt[4]{3}, the technician determines they can be added together. Based on the rules for 'like radicals,' what are the two specific components of a radical that must be identical in both terms to allow them to be combined?
