We have the following expression:
[tex](a^{12}b^{-9})\frac{c^{-6}}{\square}[/tex]Now let's recall two properties of the exponents that will help to solve this exercise:
[tex]x^{-1}=\text{ }\frac{1}{x}\Rightarrow4^{-3\text{ }}=\text{ }\frac{1}{4^3}[/tex]Then we have:
[tex]a^{12}c^6/b^9[/tex]Now, we have all the exponents with positive sign
The base of the exponents is different (a,b and c), therefore there is no additional step we can take
