Need help please not sure what the answer is

[tex] \dfrac{-8a^8b^{-2}}{10a^{-4} b^{-10}} [/tex]
[tex]= \dfrac{-8}{10} a^8b^{-2} a^{4} b^{10} [/tex]
[tex]= -\dfrac{4}{5} a^{12}b^{8}[/tex]
Answer: first choice
Answer:
It's the first choice -4 a^12b^8 / 5.
Step-by-step explanation:
- 8a^8 b^-2 / 10a^-4 b^-10
= -4 a^(8 - -4) b^(-2 - -10) / 5
= -4 a^12b^8 / 5
