hi

7. misty1212

is it really $15^{-5}$??

8. anonymous

yea\s

9. anonymous

yes

10. misty1212

ok then $15^{-5}=\frac{1}{15^5}$

11. anonymous

ok

12. misty1212

$$15^5$$i is a pretty large number so it is probably A

13. anonymous

lol a isn't a large number... its under 1

15. misty1212

actually none of those answers are correct i am going to guess that is it really $5^{-5}$

16. misty1212

since $5^5=3125$ you have $5^{-5}=\frac{1}{5^5}=\frac{1}{3125}$
