$x^{-n} = \frac{ 1 }{ x^n }$ when you are dividing and have exponents we subtract as such $\frac{ x^n }{ x^m } = x^{n-m}$ and you already know of $x^nx^m = x^{n+m}$

$\large 3^2b^2c^{-4} \times 3^{-1}b^{-5}c^7 \implies \frac{ 3^2b^2c^7 }{ 3^1b^5c^4\ }$

Look at what I said above, at some point you will have to do things on your own.
