Work Step by Step

Using $\left(\dfrac{a}{b}\right)^x=\dfrac{a^x}{b^x}$, then the expression, $ \left(\dfrac{a^3}{b^8}\right)^6 $, simplifies to \begin{array}{l}\require{cancel} \dfrac{(a^3)^6}{(b^8)^6} .\end{array} Using $(a^x)^y=a^{xy}$, then the given expression, $ \dfrac{(a^3)^6}{(b^8)^6} $, simplifies to \begin{array}{l}\require{cancel} \dfrac{a^{3(6)}}{b^{8(6)}} \\\\= \dfrac{a^{18}}{b^{48}} .\end{array}
