Question

Simplify: 2a^6 b^6)(3a^-5 b^-7)

Answer 1

Use power properties to simplify the expression:

`\begin{gathered} a^(-5)=(1)/(a^5) \\ b^(-7)=(1)/(b^7) \end{gathered}`
`\begin{gathered} (2a^6b^6)(3a^(-5)b^(-7)) \\ (2a^{6^{}}b^6)((3)/(a^5b^7)) \\ 6\cdot(a^6)/(a^5)\cdot(b^6)/(b^7) \\ (6a)/(b) \end{gathered}`
