Simplify and express with positive indices, a little help?(adsbygoogle = window.adsbygoogle || []).push({});

I am no good at these, can anyone show me how to work these out?

(18x^{3}X 2x^{-4})/(4x^{-5}X 6x)

8^{3}sqrt(p^{12}q^{-8}) X 3^{4}sqrt(p^{-10}q^{9})

and

(6^{x+2}X 4^{2x-4}X 3^{5-x}X 2^{x-6})/(12^{4x+3}X 9^{2x-3})

ps. The Capital X's are multiplication signs
