I think its D. but im not exactly sure. @Nnesha

3. Nnesha

why do you think its D ?

4. Nnesha

exponent rule!$\huge\rm \frac{ x^m }{ x^n }=x^{m-n}$

5. anonymous

When you divide with the small number ( I forgot the name ) You just subtract.

-13

7. Nnesha

how did you get that ?? 1st) move the -4 exponent to the top then think about it what number you should combine with 4 to get 9

yep right $\frac{ 8^{?} }{ 8^{-4} } = 8^{?-(-4)}=8^{?+4}$ this time i gave you hint but next you should figure it out!
