Recalling Properties for Structural Load Formulas

An engineering technician is reviewing the steps to simplify a structural load formula given by the expression u45u25u135\frac{u^{\frac{4}{5}} \cdot u^{-\frac{2}{5}}}{u^{-\frac{13}{5}}}. To begin simplifying, they must first combine the two terms in the numerator. What is the name of the mathematical property that allows the technician to combine these terms, and what specific action is taken with the exponents when this property is applied?
