Answer:
[tex]11^{-12}[/tex]
Step-by-step explanation:
what you have is the following expression:
[tex]\frac{11^{-4}}{11^{8}}[/tex]
You can aply the rule for division of powers having the same base. It says that you must left the base and substract the exponents. So it follows
[tex]\frac{11^{-4}}{11^{8}}= 11^{-4 -8}= 11^{-12}[/tex]
