Use power properties to simplify the expression:
[tex]\begin{gathered} a^{-5}=\frac{1}{a^5} \\ b^{-7}=\frac{1}{b^7} \end{gathered}[/tex][tex]\begin{gathered} (2a^6b^6)(3a^{-5}b^{-7}) \\ (2a^{6^{}}b^6)(\frac{3}{a^5b^7}) \\ 6\cdot\frac{a^6}{a^5}\cdot\frac{b^6}{b^7} \\ \frac{6a}{b} \end{gathered}[/tex]
