Here are a few rules with exponents that you need to know:
- Dividing exponents of the same base: [tex]\frac{x^m}{x^n}=x^{m-n}[/tex]
For this, divide:
[tex]\frac{-8a^8b^{-2}}{10a^{-4}b^{-10}}=\frac{-8}{10}a^{8-(-4)}b^{-2-(-10)}=-\frac{4}{5}a^{12}b^8[/tex]
Your final answer is [tex]-\frac{4}{5}a^{12}b^8[/tex]
